We look at the division of 31124785 by 304 
We want to figure out the number of times 31124785 can be divided by 304.

Advancing to step 1:
3 divided by 304 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 304

Going ahead to step 2:
The number 304 fits into 31 0 times, leaving a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 304

Advancing to step 3:
When dividing 311 by 304, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 304 from 311 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 304

Advancing to step 4:
304 can be fit into 72 0 times, resulting in a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 72 leaves us with 72.
Fetch the next digit (4) from the dividend, attach it to 72 and continue: 724 / 304

On to step 5:
The number 304 fits into 724 2 times, leaving a remainder of 116.
Put 2 as the next digit of the answer. 
Result so far: 102.0
Subtract 608 from 724 to get 116.
Bring next digit (7) of the dividend behind the 116 and repeat the process: 1167 / 304

Going ahead to step 6:
304 can be fit into 1167 3 times, resulting in a remainder of 255.
The number 3 becomes the next digit in our result. 
Result so far: 1023.0
The remainder is 255 after subtracting 912 from 1167.
Include the next digit (8) from the dividend after 255, then repeat: 2558 / 304

Let's proceed to step 7:
When dividing 2558 by 304, we get 8 with a remainder of 126.
Record the quotient 8 as the next digit in the result. 
Result so far: 10238.0
Subtract 2432 from 2558 to get 126.
Include the next digit (5) from the dividend after 126, then repeat: 1265 / 304

Advancing to step 8:
1265 divided by 304 is 4 with a remainder of 49.
The next digit of our result is 4. 
Result so far: 102384.0
If we subtract 1216 from 1265, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 9:
If we divide 490 by 304, we get 1 and a remainder of 186.
Write down 1 as next digit of the result. 
Result so far: 102384.1
Subtracting 304 from 490 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 10:
If we divide 1860 by 304, we get 6 and a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 102384.16
If we subtract 1824 from 1860, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
304 goes into 360 1 times with a remainder of 56.
The next digit of our result is 1. 
Result so far: 102384.161
If we subtract 304 from 360, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
If we divide 560 by 304, we get 1 and a remainder of 256.
The next digit of our result is 1. 
Result so far: 102384.1611
Deduct 304 from 560 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final outcome is 102384.1611, with a leftover of 0.00256.
