We look at the division of 77154748 by 455 
Our goal is to divide 77154748 by 455.

Moving on to step 1:
When dividing 7 by 455, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 455

Going ahead to step 2:
The number 455 fits into 77 0 times, leaving a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 455

Step 3:
771 divided by 455 is 1 with a remainder of 316.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 455 from 771, we get 316.
Fetch the next digit (5) from the dividend, attach it to 316 and continue: 3165 / 455

On to step 4:
When dividing 3165 by 455, we get 6 with a remainder of 435.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 435 after subtracting 2730 from 3165.
Take the next digit (4) from the dividend and append it to 435, then repeat: 4354 / 455

Advancing to step 5:
455 can be fit into 4354 9 times, resulting in a remainder of 259.
The next digit of our result is 9. 
Result so far: 169.0
If we subtract 4095 from 4354, we get 259.
Fetch the next digit (7) from the dividend, attach it to 259 and continue: 2597 / 455

Advancing to step 6:
455 goes into 2597 5 times with a remainder of 322.
Put 5 as the next digit of the answer. 
Result so far: 1695.0
The remainder is 322 after subtracting 2275 from 2597.
Grab the next digit (4) from the dividend, add it to 322, then carry on: 3224 / 455

Moving on to step 7:
455 goes into 3224 7 times with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 16957.0
Subtracting 3185 from 3224 leaves us with 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 455

Let's proceed to step 8:
The number 455 fits into 398 0 times, leaving a remainder of 398.
The next digit of our result is 0. 
Result so far: 169570.0
The remainder is 398 after subtracting 0 from 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 9:
The number 455 fits into 3980 8 times, leaving a remainder of 340.
Write down 8 as next digit of the result. 
Result so far: 169570.8
Subtract 3640 from 3980 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 10:
If we divide 3400 by 455, we get 7 and a remainder of 215.
The next digit of our result is 7. 
Result so far: 169570.87
Deduct 3185 from 3400 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 11:
If we divide 2150 by 455, we get 4 and a remainder of 330.
Write down 4 as next digit of the result. 
Result so far: 169570.874
The remainder is 330 after subtracting 1820 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 12:
455 goes into 3300 7 times with a remainder of 115.
Put 7 as the next digit of the answer. 
Result so far: 169570.8747
Subtract 3185 from 3300 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 13:
If we divide 1150 by 455, we get 2 and a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 169570.87472
If we subtract 910 from 1150, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 14:
455 goes into 2400 5 times with a remainder of 125.
The next digit of our result is 5. 
Result so far: 169570.874725
Subtracting 2275 from 2400 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 15:
455 goes into 1250 2 times with a remainder of 340.
Put 2 as the next digit of the answer. 
Result so far: 169570.8747252
Subtract 910 from 1250 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 16:
If we divide 3400 by 455, we get 7 and a remainder of 215.
Put 7 as the next digit of the answer. 
Result so far: 169570.87472527
Subtracting 3185 from 3400 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

After the division, we end up with 169570.87472527 and a remainder of 2.15e-07.
