Let's divide 31649902 by 858
We want to figure out the number of times 31649902 can be divided by 858.

Advancing to step 1:
If we divide 3 by 858, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 858

Step 2:
858 can be fit into 31 0 times, resulting in a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 858

Step 3:
When dividing 316 by 858, we get 0 with a remainder of 316.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 316 leaves us with 316.
Append the next digit (4) from the dividend to 316 and continue with: 3164 / 858

Advancing to step 4:
858 goes into 3164 3 times with a remainder of 590.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 590 after subtracting 2574 from 3164.
Take the next digit (9) from the dividend and append it to 590, then repeat: 5909 / 858

On to step 5:
5909 divided by 858 is 6 with a remainder of 761.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we subtract 5148 from 5909, we get 761.
Include the next digit (9) from the dividend after 761, then repeat: 7619 / 858

Moving on to step 6:
The number 858 fits into 7619 8 times, leaving a remainder of 755.
Record the quotient 8 as the next digit in the result. 
Result so far: 368.0
Subtracting 6864 from 7619 leaves us with 755.
Take the next digit (0) from the dividend and append it to 755, then repeat: 7550 / 858

Advancing to step 7:
If we divide 7550 by 858, we get 8 and a remainder of 686.
Write down 8 as next digit of the result. 
Result so far: 3688.0
Subtracting 6864 from 7550 leaves us with 686.
Grab the next digit (2) from the dividend, add it to 686, then carry on: 6862 / 858

Let's proceed to step 8:
If we divide 6862 by 858, we get 7 and a remainder of 856.
Record the quotient 7 as the next digit in the result. 
Result so far: 36887.0
Deduct 6006 from 6862 and we're left with 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Step 9:
8560 divided by 858 is 9 with a remainder of 838.
Write down 9 as next digit of the result. 
Result so far: 36887.9
Subtracting 7722 from 8560 leaves us with 838.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8380, and continue the process.

On to step 10:
When dividing 8380 by 858, we get 9 with a remainder of 658.
The next digit of our result is 9. 
Result so far: 36887.99
If we take 7722 away from 8380, we end up with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

The final outcome is 36887.99, with a leftover of 0.658.
