Let's divide 31543906 by 904
Our goal is to divide 31543906 by 904.

Step 1:
When dividing 3 by 904, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
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 / 904

On to step 2:
The number 904 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Append the next digit (5) from the dividend to 31 and continue with: 315 / 904

Step 3:
The number 904 fits into 315 0 times, leaving a remainder of 315.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 315, we get 315.
Grab the next digit (4) from the dividend, add it to 315, then carry on: 3154 / 904

Let's proceed to step 4:
When dividing 3154 by 904, we get 3 with a remainder of 442.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 2712 away from 3154, we end up with 442.
Take the next digit (3) from the dividend and append it to 442, then repeat: 4423 / 904

Let's proceed to step 5:
904 goes into 4423 4 times with a remainder of 807.
Put 4 as the next digit of the answer. 
Result so far: 34.0
If we subtract 3616 from 4423, we get 807.
Grab the next digit (9) from the dividend, add it to 807, then carry on: 8079 / 904

Moving on to step 6:
If we divide 8079 by 904, we get 8 and a remainder of 847.
Put 8 as the next digit of the answer. 
Result so far: 348.0
Subtracting 7232 from 8079 leaves us with 847.
Append the next digit (0) from the dividend to 847 and continue with: 8470 / 904

Step 7:
If we divide 8470 by 904, we get 9 and a remainder of 334.
Put 9 as the next digit of the answer. 
Result so far: 3489.0
Deduct 8136 from 8470 and we're left with 334.
Fetch the next digit (6) from the dividend, attach it to 334 and continue: 3346 / 904

Going ahead to step 8:
904 goes into 3346 3 times with a remainder of 634.
The number 3 becomes the next digit in our result. 
Result so far: 34893.0
The remainder is 634 after subtracting 2712 from 3346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Going ahead to step 9:
The number 904 fits into 6340 7 times, leaving a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 34893.7
The remainder is 12 after subtracting 6328 from 6340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
If we divide 120 by 904, we get 0 and a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 34893.7
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 11:
1200 divided by 904 is 1 with a remainder of 296.
Record the quotient 1 as the next digit in the result. 
Result so far: 34893.701
The remainder is 296 after subtracting 904 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 12:
904 goes into 2960 3 times with a remainder of 248.
Write down 3 as next digit of the result. 
Result so far: 34893.7013
The remainder is 248 after subtracting 2712 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 13:
When dividing 2480 by 904, we get 2 with a remainder of 672.
Write down 2 as next digit of the result. 
Result so far: 34893.70132
Deduct 1808 from 2480 and we're left with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

On to step 14:
904 goes into 6720 7 times with a remainder of 392.
Use 7 as the next digit of our solution. 
Result so far: 34893.701327
The remainder is 392 after subtracting 6328 from 6720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 15:
If we divide 3920 by 904, we get 4 and a remainder of 304.
Put 4 as the next digit of the answer. 
Result so far: 34893.7013274
Subtracting 3616 from 3920 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 16:
3040 divided by 904 is 3 with a remainder of 328.
The next digit of our result is 3. 
Result so far: 34893.70132743
Subtracting 2712 from 3040 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

After the division, we end up with 34893.70132743 and a remainder of 3.28e-07.
