We look at the division of 31355418 by 458 
Our goal is to divide 31355418 by 458.

On to step 1:
When dividing 3 by 458, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 458

Going ahead to step 2:
458 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Bring next digit (3) of the dividend behind the 31 and repeat the process: 313 / 458

Advancing to step 3:
When dividing 313 by 458, we get 0 with a remainder of 313.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 313, we end up with 313.
Include the next digit (5) from the dividend after 313, then repeat: 3135 / 458

Step 4:
458 goes into 3135 6 times with a remainder of 387.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 2748 from 3135 to get 387.
Include the next digit (5) from the dividend after 387, then repeat: 3875 / 458

Advancing to step 5:
458 goes into 3875 8 times with a remainder of 211.
The next digit of our result is 8. 
Result so far: 68.0
If we take 3664 away from 3875, we end up with 211.
Take the next digit (4) from the dividend and append it to 211, then repeat: 2114 / 458

Moving on to step 6:
458 can be fit into 2114 4 times, resulting in a remainder of 282.
The next digit of our result is 4. 
Result so far: 684.0
If we take 1832 away from 2114, we end up with 282.
Grab the next digit (1) from the dividend, add it to 282, then carry on: 2821 / 458

Advancing to step 7:
The number 458 fits into 2821 6 times, leaving a remainder of 73.
Write down 6 as next digit of the result. 
Result so far: 6846.0
The remainder is 73 after subtracting 2748 from 2821.
Fetch the next digit (8) from the dividend, attach it to 73 and continue: 738 / 458

Going ahead to step 8:
If we divide 738 by 458, we get 1 and a remainder of 280.
Put 1 as the next digit of the answer. 
Result so far: 68461.0
If we subtract 458 from 738, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 9:
2800 divided by 458 is 6 with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 68461.6
Deduct 2748 from 2800 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
458 can be fit into 520 1 times, resulting in a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 68461.61
If we subtract 458 from 520, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 11:
The number 458 fits into 620 1 times, leaving a remainder of 162.
Write down 1 as next digit of the result. 
Result so far: 68461.611
Subtract 458 from 620 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

After the division, we end up with 68461.611 and a remainder of 0.0162.
