78768118 ÷ 455 
We want to divide 78768118 by 455.

Moving on to step 1:
7 divided by 455 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 455

Let's proceed to step 2:
78 divided by 455 is 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Append the next digit (7) from the dividend to 78 and continue with: 787 / 455

Going ahead to step 3:
787 divided by 455 is 1 with a remainder of 332.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 455 away from 787, we end up with 332.
Append the next digit (6) from the dividend to 332 and continue with: 3326 / 455

On to step 4:
3326 divided by 455 is 7 with a remainder of 141.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 3185 from 3326 leaves us with 141.
Fetch the next digit (8) from the dividend, attach it to 141 and continue: 1418 / 455

On to step 5:
When dividing 1418 by 455, we get 3 with a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 173.0
The remainder is 53 after subtracting 1365 from 1418.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 455

Let's proceed to step 6:
455 goes into 531 1 times with a remainder of 76.
The next digit of our result is 1. 
Result so far: 1731.0
Deduct 455 from 531 and we're left with 76.
Take the next digit (1) from the dividend and append it to 76, then repeat: 761 / 455

Moving on to step 7:
The number 455 fits into 761 1 times, leaving a remainder of 306.
Record the quotient 1 as the next digit in the result. 
Result so far: 17311.0
Deduct 455 from 761 and we're left with 306.
Append the next digit (8) from the dividend to 306 and continue with: 3068 / 455

On to step 8:
455 can be fit into 3068 6 times, resulting in a remainder of 338.
Write down 6 as next digit of the result. 
Result so far: 173116.0
If we take 2730 away from 3068, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Let's proceed to step 9:
455 can be fit into 3380 7 times, resulting in a remainder of 195.
Record the quotient 7 as the next digit in the result. 
Result so far: 173116.7
Deduct 3185 from 3380 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 10:
If we divide 1950 by 455, we get 4 and a remainder of 130.
Write down 4 as next digit of the result. 
Result so far: 173116.74
The remainder is 130 after subtracting 1820 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 11:
The number 455 fits into 1300 2 times, leaving a remainder of 390.
The next digit of our result is 2. 
Result so far: 173116.742
The remainder is 390 after subtracting 910 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 12:
455 goes into 3900 8 times with a remainder of 260.
Use 8 as the next digit of our solution. 
Result so far: 173116.7428
The remainder is 260 after subtracting 3640 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 13:
455 can be fit into 2600 5 times, resulting in a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 173116.74285
Subtract 2275 from 2600 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Let's proceed to step 14:
455 can be fit into 3250 7 times, resulting in a remainder of 65.
The next digit of our result is 7. 
Result so far: 173116.742857
The remainder is 65 after subtracting 3185 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 15:
455 can be fit into 650 1 times, resulting in a remainder of 195.
Record the quotient 1 as the next digit in the result. 
Result so far: 173116.7428571
The remainder is 195 after subtracting 455 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 16:
455 can be fit into 1950 4 times, resulting in a remainder of 130.
The number 4 becomes the next digit in our result. 
Result so far: 173116.74285714
The remainder is 130 after subtracting 1820 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final result is 173116.74285714 with a remainder of 1.3e-07.
