Let's divide 78402582 by 455
We're looking to find how many times 455 goes into 78402582.

Moving on to step 1:
The number 455 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 455

Step 2:
If we divide 78 by 455, we get 0 and a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 455

On to step 3:
455 goes into 784 1 times with a remainder of 329.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 455 from 784 leaves us with 329.
Take the next digit (0) from the dividend and append it to 329, then repeat: 3290 / 455

Advancing to step 4:
When dividing 3290 by 455, we get 7 with a remainder of 105.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 3185 from 3290, we get 105.
Bring next digit (2) of the dividend behind the 105 and repeat the process: 1052 / 455

Advancing to step 5:
If we divide 1052 by 455, we get 2 and a remainder of 142.
Record the quotient 2 as the next digit in the result. 
Result so far: 172.0
Subtracting 910 from 1052 leaves us with 142.
Take the next digit (5) from the dividend and append it to 142, then repeat: 1425 / 455

Step 6:
455 can be fit into 1425 3 times, resulting in a remainder of 60.
The next digit of our result is 3. 
Result so far: 1723.0
If we subtract 1365 from 1425, we get 60.
Fetch the next digit (8) from the dividend, attach it to 60 and continue: 608 / 455

Step 7:
When dividing 608 by 455, we get 1 with a remainder of 153.
The next digit of our result is 1. 
Result so far: 17231.0
The remainder is 153 after subtracting 455 from 608.
Fetch the next digit (2) from the dividend, attach it to 153 and continue: 1532 / 455

Moving on to step 8:
The number 455 fits into 1532 3 times, leaving a remainder of 167.
The number 3 becomes the next digit in our result. 
Result so far: 172313.0
Subtract 1365 from 1532 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Step 9:
1670 divided by 455 is 3 with a remainder of 305.
Use 3 as the next digit of our solution. 
Result so far: 172313.3
The remainder is 305 after subtracting 1365 from 1670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 10:
When dividing 3050 by 455, we get 6 with a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 172313.36
Subtract 2730 from 3050 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 11:
If we divide 3200 by 455, we get 7 and a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 172313.367
Subtract 3185 from 3200 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
455 can be fit into 150 0 times, resulting in a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 172313.367
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 13:
455 goes into 1500 3 times with a remainder of 135.
Write down 3 as next digit of the result. 
Result so far: 172313.36703
The remainder is 135 after subtracting 1365 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 14:
When dividing 1350 by 455, we get 2 with a remainder of 440.
Put 2 as the next digit of the answer. 
Result so far: 172313.367032
If we subtract 910 from 1350, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 15:
When dividing 4400 by 455, we get 9 with a remainder of 305.
The next digit of our result is 9. 
Result so far: 172313.3670329
Deduct 4095 from 4400 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 16:
The number 455 fits into 3050 6 times, leaving a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 172313.36703296
If we take 2730 away from 3050, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The quotient of the division is 172313.36703296, and the remainder is 3.2e-07.
