31786669 ÷ 904 
We want to figure out the number of times 31786669 can be divided by 904.

On to step 1:
If we divide 3 by 904, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 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.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 904

Advancing to step 3:
The number 904 fits into 317 0 times, leaving a remainder of 317.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 317 after subtracting 0 from 317.
Bring next digit (8) of the dividend behind the 317 and repeat the process: 3178 / 904

Step 4:
904 can be fit into 3178 3 times, resulting in a remainder of 466.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 2712 from 3178 leaves us with 466.
Append the next digit (6) from the dividend to 466 and continue with: 4666 / 904

On to step 5:
If we divide 4666 by 904, we get 5 and a remainder of 146.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Subtracting 4520 from 4666 leaves us with 146.
Include the next digit (6) from the dividend after 146, then repeat: 1466 / 904

On to step 6:
1466 divided by 904 is 1 with a remainder of 562.
The next digit of our result is 1. 
Result so far: 351.0
Deduct 904 from 1466 and we're left with 562.
Bring next digit (6) of the dividend behind the 562 and repeat the process: 5626 / 904

Moving on to step 7:
When dividing 5626 by 904, we get 6 with a remainder of 202.
Use 6 as the next digit of our solution. 
Result so far: 3516.0
Subtract 5424 from 5626 to get 202.
Grab the next digit (9) from the dividend, add it to 202, then carry on: 2029 / 904

On to step 8:
904 can be fit into 2029 2 times, resulting in a remainder of 221.
Use 2 as the next digit of our solution. 
Result so far: 35162.0
The remainder is 221 after subtracting 1808 from 2029.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Step 9:
904 goes into 2210 2 times with a remainder of 402.
Write down 2 as next digit of the result. 
Result so far: 35162.2
Deduct 1808 from 2210 and we're left with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

On to step 10:
904 can be fit into 4020 4 times, resulting in a remainder of 404.
Record the quotient 4 as the next digit in the result. 
Result so far: 35162.24
The remainder is 404 after subtracting 3616 from 4020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 11:
When dividing 4040 by 904, we get 4 with a remainder of 424.
Write down 4 as next digit of the result. 
Result so far: 35162.244
Subtract 3616 from 4040 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

The final outcome is 35162.244, with a leftover of 0.0424.
