Let's divide 87105862 by 899
We want to figure out the number of times 87105862 can be divided by 899.

On to step 1:
8 divided by 899 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 899

Step 2:
If we divide 87 by 899, we get 0 and a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Fetch the next digit (1) from the dividend, attach it to 87 and continue: 871 / 899

Advancing to step 3:
If we divide 871 by 899, we get 0 and a remainder of 871.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 871 after subtracting 0 from 871.
Include the next digit (0) from the dividend after 871, then repeat: 8710 / 899

On to step 4:
899 can be fit into 8710 9 times, resulting in a remainder of 619.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 8091 away from 8710, we end up with 619.
Take the next digit (5) from the dividend and append it to 619, then repeat: 6195 / 899

Advancing to step 5:
899 can be fit into 6195 6 times, resulting in a remainder of 801.
Use 6 as the next digit of our solution. 
Result so far: 96.0
If we take 5394 away from 6195, we end up with 801.
Bring next digit (8) of the dividend behind the 801 and repeat the process: 8018 / 899

Going ahead to step 6:
899 can be fit into 8018 8 times, resulting in a remainder of 826.
Record the quotient 8 as the next digit in the result. 
Result so far: 968.0
If we subtract 7192 from 8018, we get 826.
Fetch the next digit (6) from the dividend, attach it to 826 and continue: 8266 / 899

Going ahead to step 7:
899 goes into 8266 9 times with a remainder of 175.
The next digit of our result is 9. 
Result so far: 9689.0
If we subtract 8091 from 8266, we get 175.
Grab the next digit (2) from the dividend, add it to 175, then carry on: 1752 / 899

Going ahead to step 8:
899 goes into 1752 1 times with a remainder of 853.
Use 1 as the next digit of our solution. 
Result so far: 96891.0
If we subtract 899 from 1752, we get 853.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8530, and continue the process.

On to step 9:
When dividing 8530 by 899, we get 9 with a remainder of 439.
The number 9 becomes the next digit in our result. 
Result so far: 96891.9
If we take 8091 away from 8530, we end up with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Advancing to step 10:
The number 899 fits into 4390 4 times, leaving a remainder of 794.
Use 4 as the next digit of our solution. 
Result so far: 96891.94
If we take 3596 away from 4390, we end up with 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Going ahead to step 11:
7940 divided by 899 is 8 with a remainder of 748.
The next digit of our result is 8. 
Result so far: 96891.948
Deduct 7192 from 7940 and we're left with 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Going ahead to step 12:
899 goes into 7480 8 times with a remainder of 288.
The number 8 becomes the next digit in our result. 
Result so far: 96891.9488
If we take 7192 away from 7480, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final result is 96891.9488 with a remainder of 0.00288.
