Let's divide 86021303 by 836
Let's see how many times 836 fits into 86021303.

Step 1:
The number 836 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 836

Step 2:
836 goes into 86 0 times with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Fetch the next digit (0) from the dividend, attach it to 86 and continue: 860 / 836

Advancing to step 3:
836 goes into 860 1 times with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 836 from 860 leaves us with 24.
Include the next digit (2) from the dividend after 24, then repeat: 242 / 836

Advancing to step 4:
836 goes into 242 0 times with a remainder of 242.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 242 to get 242.
Grab the next digit (1) from the dividend, add it to 242, then carry on: 2421 / 836

Advancing to step 5:
The number 836 fits into 2421 2 times, leaving a remainder of 749.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Subtract 1672 from 2421 to get 749.
Append the next digit (3) from the dividend to 749 and continue with: 7493 / 836

Step 6:
If we divide 7493 by 836, we get 8 and a remainder of 805.
Use 8 as the next digit of our solution. 
Result so far: 1028.0
Subtracting 6688 from 7493 leaves us with 805.
Take the next digit (0) from the dividend and append it to 805, then repeat: 8050 / 836

Step 7:
836 goes into 8050 9 times with a remainder of 526.
The number 9 becomes the next digit in our result. 
Result so far: 10289.0
Subtracting 7524 from 8050 leaves us with 526.
Include the next digit (3) from the dividend after 526, then repeat: 5263 / 836

Going ahead to step 8:
836 goes into 5263 6 times with a remainder of 247.
Record the quotient 6 as the next digit in the result. 
Result so far: 102896.0
If we subtract 5016 from 5263, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

On to step 9:
2470 divided by 836 is 2 with a remainder of 798.
The number 2 becomes the next digit in our result. 
Result so far: 102896.2
The remainder is 798 after subtracting 1672 from 2470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Advancing to step 10:
836 can be fit into 7980 9 times, resulting in a remainder of 456.
Put 9 as the next digit of the answer. 
Result so far: 102896.29
Subtract 7524 from 7980 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Step 11:
When dividing 4560 by 836, we get 5 with a remainder of 380.
Use 5 as the next digit of our solution. 
Result so far: 102896.295
The remainder is 380 after subtracting 4180 from 4560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 12:
The number 836 fits into 3800 4 times, leaving a remainder of 456.
Write down 4 as next digit of the result. 
Result so far: 102896.2954
Deduct 3344 from 3800 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Step 13:
When dividing 4560 by 836, we get 5 with a remainder of 380.
The next digit of our result is 5. 
Result so far: 102896.29545
Subtracting 4180 from 4560 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 14:
The number 836 fits into 3800 4 times, leaving a remainder of 456.
Write down 4 as next digit of the result. 
Result so far: 102896.295454
Deduct 3344 from 3800 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

On to step 15:
836 can be fit into 4560 5 times, resulting in a remainder of 380.
Put 5 as the next digit of the answer. 
Result so far: 102896.2954545
If we take 4180 away from 4560, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 16:
If we divide 3800 by 836, we get 4 and a remainder of 456.
Write down 4 as next digit of the result. 
Result so far: 102896.29545454
The remainder is 456 after subtracting 3344 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

The final result is 102896.29545454 with a remainder of 4.56e-07.
