We're dividing 31029820 by 858 
We're looking to find how many times 858 goes into 31029820.

On to step 1:
When dividing 3 by 858, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 858

Advancing to step 2:
If we divide 31 by 858, we get 0 and a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 858

Advancing to step 3:
310 divided by 858 is 0 with a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 310 and we're left with 310.
Grab the next digit (2) from the dividend, add it to 310, then carry on: 3102 / 858

Moving on to step 4:
858 goes into 3102 3 times with a remainder of 528.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 2574 from 3102 and we're left with 528.
Fetch the next digit (9) from the dividend, attach it to 528 and continue: 5289 / 858

Advancing to step 5:
The number 858 fits into 5289 6 times, leaving a remainder of 141.
Write down 6 as next digit of the result. 
Result so far: 36.0
If we take 5148 away from 5289, we end up with 141.
Bring next digit (8) of the dividend behind the 141 and repeat the process: 1418 / 858

Advancing to step 6:
858 can be fit into 1418 1 times, resulting in a remainder of 560.
The number 1 becomes the next digit in our result. 
Result so far: 361.0
The remainder is 560 after subtracting 858 from 1418.
Include the next digit (2) from the dividend after 560, then repeat: 5602 / 858

Advancing to step 7:
5602 divided by 858 is 6 with a remainder of 454.
Use 6 as the next digit of our solution. 
Result so far: 3616.0
The remainder is 454 after subtracting 5148 from 5602.
Append the next digit (0) from the dividend to 454 and continue with: 4540 / 858

Step 8:
858 can be fit into 4540 5 times, resulting in a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 36165.0
Deduct 4290 from 4540 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 9:
When dividing 2500 by 858, we get 2 with a remainder of 784.
The next digit of our result is 2. 
Result so far: 36165.2
Subtract 1716 from 2500 to get 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Advancing to step 10:
If we divide 7840 by 858, we get 9 and a remainder of 118.
Put 9 as the next digit of the answer. 
Result so far: 36165.29
If we take 7722 away from 7840, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 11:
1180 divided by 858 is 1 with a remainder of 322.
The number 1 becomes the next digit in our result. 
Result so far: 36165.291
Subtract 858 from 1180 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 12:
When dividing 3220 by 858, we get 3 with a remainder of 646.
Use 3 as the next digit of our solution. 
Result so far: 36165.2913
Subtracting 2574 from 3220 leaves us with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Moving on to step 13:
858 can be fit into 6460 7 times, resulting in a remainder of 454.
Put 7 as the next digit of the answer. 
Result so far: 36165.29137
If we subtract 6006 from 6460, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

On to step 14:
4540 divided by 858 is 5 with a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 36165.291375
If we subtract 4290 from 4540, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 15:
2500 divided by 858 is 2 with a remainder of 784.
The next digit of our result is 2. 
Result so far: 36165.2913752
Subtracting 1716 from 2500 leaves us with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

On to step 16:
The number 858 fits into 7840 9 times, leaving a remainder of 118.
Record the quotient 9 as the next digit in the result. 
Result so far: 36165.29137529
The remainder is 118 after subtracting 7722 from 7840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

The final result is 36165.29137529 with a remainder of 1.18e-07.
