87070642 ÷ 836 
We want to divide 87070642 by 836.

On to 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
The remainder is 8 after subtracting 0 from 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 836

Moving on to step 2:
87 divided by 836 is 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Append the next digit (0) from the dividend to 87 and continue with: 870 / 836

Moving on to step 3:
If we divide 870 by 836, we get 1 and a remainder of 34.
The next digit of our result is 1. 
Result so far: 1.0
If we take 836 away from 870, we end up with 34.
Fetch the next digit (7) from the dividend, attach it to 34 and continue: 347 / 836

On to step 4:
347 divided by 836 is 0 with a remainder of 347.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 347 after subtracting 0 from 347.
Fetch the next digit (0) from the dividend, attach it to 347 and continue: 3470 / 836

Moving on to step 5:
836 goes into 3470 4 times with a remainder of 126.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
Subtracting 3344 from 3470 leaves us with 126.
Take the next digit (6) from the dividend and append it to 126, then repeat: 1266 / 836

Going ahead to step 6:
836 can be fit into 1266 1 times, resulting in a remainder of 430.
Put 1 as the next digit of the answer. 
Result so far: 1041.0
If we subtract 836 from 1266, we get 430.
Fetch the next digit (4) from the dividend, attach it to 430 and continue: 4304 / 836

Let's proceed to step 7:
When dividing 4304 by 836, we get 5 with a remainder of 124.
Put 5 as the next digit of the answer. 
Result so far: 10415.0
If we take 4180 away from 4304, we end up with 124.
Grab the next digit (2) from the dividend, add it to 124, then carry on: 1242 / 836

Let's proceed to step 8:
1242 divided by 836 is 1 with a remainder of 406.
The number 1 becomes the next digit in our result. 
Result so far: 104151.0
Deduct 836 from 1242 and we're left with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Advancing to step 9:
If we divide 4060 by 836, we get 4 and a remainder of 716.
Put 4 as the next digit of the answer. 
Result so far: 104151.4
The remainder is 716 after subtracting 3344 from 4060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Moving on to step 10:
7160 divided by 836 is 8 with a remainder of 472.
The next digit of our result is 8. 
Result so far: 104151.48
Deduct 6688 from 7160 and we're left with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 11:
836 can be fit into 4720 5 times, resulting in a remainder of 540.
Use 5 as the next digit of our solution. 
Result so far: 104151.485
If we subtract 4180 from 4720, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 12:
If we divide 5400 by 836, we get 6 and a remainder of 384.
The next digit of our result is 6. 
Result so far: 104151.4856
Deduct 5016 from 5400 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 13:
When dividing 3840 by 836, we get 4 with a remainder of 496.
Put 4 as the next digit of the answer. 
Result so far: 104151.48564
The remainder is 496 after subtracting 3344 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 14:
The number 836 fits into 4960 5 times, leaving a remainder of 780.
The number 5 becomes the next digit in our result. 
Result so far: 104151.485645
If we take 4180 away from 4960, we end up with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Moving on to step 15:
When dividing 7800 by 836, we get 9 with a remainder of 276.
Write down 9 as next digit of the result. 
Result so far: 104151.4856459
Deduct 7524 from 7800 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 16:
2760 divided by 836 is 3 with a remainder of 252.
Put 3 as the next digit of the answer. 
Result so far: 104151.48564593
Deduct 2508 from 2760 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The final outcome is 104151.48564593, with a leftover of 2.52e-07.
