Let's divide 89589391 by 899
We want to figure out the number of times 89589391 can be divided by 899.

Going ahead to step 1:
8 divided by 899 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 899

Going ahead to step 2:
If we divide 89 by 899, we get 0 and a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Include the next digit (5) from the dividend after 89, then repeat: 895 / 899

Moving on to step 3:
If we divide 895 by 899, we get 0 and a remainder of 895.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 895 leaves us with 895.
Bring next digit (8) of the dividend behind the 895 and repeat the process: 8958 / 899

Advancing to step 4:
899 goes into 8958 9 times with a remainder of 867.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 8091 from 8958 to get 867.
Fetch the next digit (9) from the dividend, attach it to 867 and continue: 8679 / 899

Going ahead to step 5:
899 goes into 8679 9 times with a remainder of 588.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtracting 8091 from 8679 leaves us with 588.
Bring next digit (3) of the dividend behind the 588 and repeat the process: 5883 / 899

Step 6:
899 can be fit into 5883 6 times, resulting in a remainder of 489.
Put 6 as the next digit of the answer. 
Result so far: 996.0
The remainder is 489 after subtracting 5394 from 5883.
Bring next digit (9) of the dividend behind the 489 and repeat the process: 4899 / 899

Going ahead to step 7:
899 can be fit into 4899 5 times, resulting in a remainder of 404.
Record the quotient 5 as the next digit in the result. 
Result so far: 9965.0
If we take 4495 away from 4899, we end up with 404.
Append the next digit (1) from the dividend to 404 and continue with: 4041 / 899

Advancing to step 8:
The number 899 fits into 4041 4 times, leaving a remainder of 445.
Write down 4 as next digit of the result. 
Result so far: 99654.0
Subtract 3596 from 4041 to get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Going ahead to step 9:
4450 divided by 899 is 4 with a remainder of 854.
The next digit of our result is 4. 
Result so far: 99654.4
Subtracting 3596 from 4450 leaves us with 854.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8540, and continue the process.

Going ahead to step 10:
8540 divided by 899 is 9 with a remainder of 449.
Record the quotient 9 as the next digit in the result. 
Result so far: 99654.49
The remainder is 449 after subtracting 8091 from 8540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Moving on to step 11:
4490 divided by 899 is 4 with a remainder of 894.
Use 4 as the next digit of our solution. 
Result so far: 99654.494
If we take 3596 away from 4490, we end up with 894.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8940, and continue the process.

Moving on to step 12:
899 goes into 8940 9 times with a remainder of 849.
Use 9 as the next digit of our solution. 
Result so far: 99654.4949
Deduct 8091 from 8940 and we're left with 849.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8490, and continue the process.

Moving on to step 13:
When dividing 8490 by 899, we get 9 with a remainder of 399.
Use 9 as the next digit of our solution. 
Result so far: 99654.49499
The remainder is 399 after subtracting 8091 from 8490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

After the division, we end up with 99654.49499 and a remainder of 0.000399.
