We're dividing 78201891 by 936 
Our goal is to divide 78201891 by 936.

Going ahead to step 1:
If we divide 7 by 936, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 936

Going ahead to step 2:
936 goes into 78 0 times with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Take the next digit (2) from the dividend and append it to 78, then repeat: 782 / 936

Step 3:
When dividing 782 by 936, we get 0 with a remainder of 782.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 782 after subtracting 0 from 782.
Fetch the next digit (0) from the dividend, attach it to 782 and continue: 7820 / 936

Going ahead to step 4:
When dividing 7820 by 936, we get 8 with a remainder of 332.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 7488 from 7820, we get 332.
Include the next digit (1) from the dividend after 332, then repeat: 3321 / 936

On to step 5:
936 can be fit into 3321 3 times, resulting in a remainder of 513.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
The remainder is 513 after subtracting 2808 from 3321.
Grab the next digit (8) from the dividend, add it to 513, then carry on: 5138 / 936

Going ahead to step 6:
When dividing 5138 by 936, we get 5 with a remainder of 458.
Record the quotient 5 as the next digit in the result. 
Result so far: 835.0
Subtracting 4680 from 5138 leaves us with 458.
Take the next digit (9) from the dividend and append it to 458, then repeat: 4589 / 936

Step 7:
4589 divided by 936 is 4 with a remainder of 845.
The next digit of our result is 4. 
Result so far: 8354.0
If we subtract 3744 from 4589, we get 845.
Fetch the next digit (1) from the dividend, attach it to 845 and continue: 8451 / 936

Let's proceed to step 8:
When dividing 8451 by 936, we get 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 83549.0
If we take 8424 away from 8451, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 9:
If we divide 270 by 936, we get 0 and a remainder of 270.
Record the quotient 0 as the next digit in the result. 
Result so far: 83549.0
If we subtract 0 from 270, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 10:
When dividing 2700 by 936, we get 2 with a remainder of 828.
Record the quotient 2 as the next digit in the result. 
Result so far: 83549.02
Subtract 1872 from 2700 to get 828.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8280, and continue the process.

Going ahead to step 11:
936 goes into 8280 8 times with a remainder of 792.
Use 8 as the next digit of our solution. 
Result so far: 83549.028
Subtract 7488 from 8280 to get 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Advancing to step 12:
When dividing 7920 by 936, we get 8 with a remainder of 432.
Record the quotient 8 as the next digit in the result. 
Result so far: 83549.0288
If we subtract 7488 from 7920, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

In conclusion, the division gives 83549.0288 with a balance of 0.00432.
