We look at the division of 31391825 by 455 
We want to divide 31391825 by 455.

Let's proceed to step 1:
3 divided by 455 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 455

Step 2:
31 divided by 455 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 455

Advancing to step 3:
455 can be fit into 313 0 times, resulting in a remainder of 313.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 313 and we're left with 313.
Include the next digit (9) from the dividend after 313, then repeat: 3139 / 455

Advancing to step 4:
455 goes into 3139 6 times with a remainder of 409.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 2730 from 3139 to get 409.
Bring next digit (1) of the dividend behind the 409 and repeat the process: 4091 / 455

Moving on to step 5:
If we divide 4091 by 455, we get 8 and a remainder of 451.
The next digit of our result is 8. 
Result so far: 68.0
The remainder is 451 after subtracting 3640 from 4091.
Grab the next digit (8) from the dividend, add it to 451, then carry on: 4518 / 455

Let's proceed to step 6:
455 goes into 4518 9 times with a remainder of 423.
Use 9 as the next digit of our solution. 
Result so far: 689.0
Subtract 4095 from 4518 to get 423.
Bring next digit (2) of the dividend behind the 423 and repeat the process: 4232 / 455

Advancing to step 7:
When dividing 4232 by 455, we get 9 with a remainder of 137.
The next digit of our result is 9. 
Result so far: 6899.0
Deduct 4095 from 4232 and we're left with 137.
Append the next digit (5) from the dividend to 137 and continue with: 1375 / 455

Moving on to step 8:
When dividing 1375 by 455, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 68993.0
The remainder is 10 after subtracting 1365 from 1375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
If we divide 100 by 455, we get 0 and a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 68993.0
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
455 can be fit into 1000 2 times, resulting in a remainder of 90.
Use 2 as the next digit of our solution. 
Result so far: 68993.02
Subtract 910 from 1000 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 11:
455 goes into 900 1 times with a remainder of 445.
The next digit of our result is 1. 
Result so far: 68993.021
Subtracting 455 from 900 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Moving on to step 12:
If we divide 4450 by 455, we get 9 and a remainder of 355.
Put 9 as the next digit of the answer. 
Result so far: 68993.0219
Deduct 4095 from 4450 and we're left with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

On to step 13:
The number 455 fits into 3550 7 times, leaving a remainder of 365.
Use 7 as the next digit of our solution. 
Result so far: 68993.02197
If we take 3185 away from 3550, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Going ahead to step 14:
If we divide 3650 by 455, we get 8 and a remainder of 10.
The next digit of our result is 8. 
Result so far: 68993.021978
Deduct 3640 from 3650 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 15:
The number 455 fits into 100 0 times, leaving a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 68993.021978
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 16:
455 goes into 1000 2 times with a remainder of 90.
Use 2 as the next digit of our solution. 
Result so far: 68993.02197802
The remainder is 90 after subtracting 910 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Our division results in 68993.02197802 with a remaining 9e-08.
