We're dividing 12904631 by 356 
We're looking to find how many times 356 goes into 12904631.

Moving on to step 1:
The number 356 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 356

Moving on to step 2:
When dividing 12 by 356, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 356

Step 3:
The number 356 fits into 129 0 times, leaving a remainder of 129.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 129 to get 129.
Bring next digit (0) of the dividend behind the 129 and repeat the process: 1290 / 356

Going ahead to step 4:
356 goes into 1290 3 times with a remainder of 222.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 1068 away from 1290, we end up with 222.
Grab the next digit (4) from the dividend, add it to 222, then carry on: 2224 / 356

On to step 5:
356 goes into 2224 6 times with a remainder of 88.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we subtract 2136 from 2224, we get 88.
Bring next digit (6) of the dividend behind the 88 and repeat the process: 886 / 356

Moving on to step 6:
When dividing 886 by 356, we get 2 with a remainder of 174.
The number 2 becomes the next digit in our result. 
Result so far: 362.0
The remainder is 174 after subtracting 712 from 886.
Bring next digit (3) of the dividend behind the 174 and repeat the process: 1743 / 356

Step 7:
When dividing 1743 by 356, we get 4 with a remainder of 319.
Record the quotient 4 as the next digit in the result. 
Result so far: 3624.0
Deduct 1424 from 1743 and we're left with 319.
Bring next digit (1) of the dividend behind the 319 and repeat the process: 3191 / 356

On to step 8:
356 goes into 3191 8 times with a remainder of 343.
Put 8 as the next digit of the answer. 
Result so far: 36248.0
Subtracting 2848 from 3191 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Moving on to step 9:
356 goes into 3430 9 times with a remainder of 226.
The next digit of our result is 9. 
Result so far: 36248.9
Subtract 3204 from 3430 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 10:
356 goes into 2260 6 times with a remainder of 124.
Record the quotient 6 as the next digit in the result. 
Result so far: 36248.96
If we subtract 2136 from 2260, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 11:
When dividing 1240 by 356, we get 3 with a remainder of 172.
Write down 3 as next digit of the result. 
Result so far: 36248.963
If we subtract 1068 from 1240, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 12:
1720 divided by 356 is 4 with a remainder of 296.
Write down 4 as next digit of the result. 
Result so far: 36248.9634
If we take 1424 away from 1720, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 13:
When dividing 2960 by 356, we get 8 with a remainder of 112.
Write down 8 as next digit of the result. 
Result so far: 36248.96348
The remainder is 112 after subtracting 2848 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 14:
356 can be fit into 1120 3 times, resulting in a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 36248.963483
If we take 1068 away from 1120, we end up 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.

Let's proceed to step 15:
If we divide 520 by 356, we get 1 and a remainder of 164.
Write down 1 as next digit of the result. 
Result so far: 36248.9634831
If we take 356 away from 520, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 16:
356 can be fit into 1640 4 times, resulting in a remainder of 216.
The next digit of our result is 4. 
Result so far: 36248.96348314
If we take 1424 away from 1640, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

The quotient of the division is 36248.96348314, and the remainder is 2.16e-07.
