Let's divide 78158211 by 872
We're looking to find how many times 872 goes into 78158211.

Advancing to step 1:
872 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 872

Going ahead to step 2:
872 can be fit into 78 0 times, resulting in a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Append the next digit (1) from the dividend to 78 and continue with: 781 / 872

Step 3:
872 can be fit into 781 0 times, resulting in a remainder of 781.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 781 to get 781.
Grab the next digit (5) from the dividend, add it to 781, then carry on: 7815 / 872

Advancing to step 4:
872 can be fit into 7815 8 times, resulting in a remainder of 839.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 6976 away from 7815, we end up with 839.
Fetch the next digit (8) from the dividend, attach it to 839 and continue: 8398 / 872

Let's proceed to step 5:
If we divide 8398 by 872, we get 9 and a remainder of 550.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Subtract 7848 from 8398 to get 550.
Append the next digit (2) from the dividend to 550 and continue with: 5502 / 872

Step 6:
872 can be fit into 5502 6 times, resulting in a remainder of 270.
Use 6 as the next digit of our solution. 
Result so far: 896.0
Subtracting 5232 from 5502 leaves us with 270.
Append the next digit (1) from the dividend to 270 and continue with: 2701 / 872

Step 7:
When dividing 2701 by 872, we get 3 with a remainder of 85.
The next digit of our result is 3. 
Result so far: 8963.0
Subtract 2616 from 2701 to get 85.
Include the next digit (1) from the dividend after 85, then repeat: 851 / 872

Advancing to step 8:
When dividing 851 by 872, we get 0 with a remainder of 851.
Record the quotient 0 as the next digit in the result. 
Result so far: 89630.0
Subtracting 0 from 851 leaves us with 851.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8510, and continue the process.

Advancing to step 9:
If we divide 8510 by 872, we get 9 and a remainder of 662.
Use 9 as the next digit of our solution. 
Result so far: 89630.9
The remainder is 662 after subtracting 7848 from 8510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Moving on to step 10:
If we divide 6620 by 872, we get 7 and a remainder of 516.
Record the quotient 7 as the next digit in the result. 
Result so far: 89630.97
Subtract 6104 from 6620 to get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Advancing to step 11:
The number 872 fits into 5160 5 times, leaving a remainder of 800.
Put 5 as the next digit of the answer. 
Result so far: 89630.975
Subtracting 4360 from 5160 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Advancing to step 12:
If we divide 8000 by 872, we get 9 and a remainder of 152.
Use 9 as the next digit of our solution. 
Result so far: 89630.9759
Subtract 7848 from 8000 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 13:
The number 872 fits into 1520 1 times, leaving a remainder of 648.
Write down 1 as next digit of the result. 
Result so far: 89630.97591
If we subtract 872 from 1520, we get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Let's proceed to step 14:
872 goes into 6480 7 times with a remainder of 376.
Use 7 as the next digit of our solution. 
Result so far: 89630.975917
Subtract 6104 from 6480 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 15:
872 goes into 3760 4 times with a remainder of 272.
Write down 4 as next digit of the result. 
Result so far: 89630.9759174
Deduct 3488 from 3760 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 16:
872 can be fit into 2720 3 times, resulting in a remainder of 104.
Write down 3 as next digit of the result. 
Result so far: 89630.97591743
If we subtract 2616 from 2720, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final outcome is 89630.97591743, with a leftover of 1.04e-07.
