We're dividing 870445 by 99 
We want to figure out the number of times 870445 can be divided by 99.

On to step 1:
99 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 99

Advancing to step 2:
The number 99 fits into 87 0 times, leaving a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Take the next digit (0) from the dividend and append it to 87, then repeat: 870 / 99

Moving on to step 3:
870 divided by 99 is 8 with a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 792 from 870 leaves us with 78.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 99

Step 4:
The number 99 fits into 784 7 times, leaving a remainder of 91.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we take 693 away from 784, we end up with 91.
Grab the next digit (4) from the dividend, add it to 91, then carry on: 914 / 99

Moving on to step 5:
The number 99 fits into 914 9 times, leaving a remainder of 23.
The next digit of our result is 9. 
Result so far: 879.0
Subtract 891 from 914 to get 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 99

Going ahead to step 6:
The number 99 fits into 235 2 times, leaving a remainder of 37.
Write down 2 as next digit of the result. 
Result so far: 8792.0
Subtract 198 from 235 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
99 can be fit into 370 3 times, resulting in a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 8792.3
The remainder is 73 after subtracting 297 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 8:
730 divided by 99 is 7 with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 8792.37
Subtract 693 from 730 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
99 can be fit into 370 3 times, resulting in a remainder of 73.
Put 3 as the next digit of the answer. 
Result so far: 8792.373
Subtract 297 from 370 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 10:
When dividing 730 by 99, we get 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 8792.3737
If we take 693 away from 730, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 11:
When dividing 370 by 99, we get 3 with a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 8792.37373
If we subtract 297 from 370, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 12:
99 can be fit into 730 7 times, resulting in a remainder of 37.
The next digit of our result is 7. 
Result so far: 8792.373737
Deduct 693 from 730 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 13:
370 divided by 99 is 3 with a remainder of 73.
The next digit of our result is 3. 
Result so far: 8792.3737373
Subtract 297 from 370 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 14:
If we divide 730 by 99, we get 7 and a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 8792.37373737
Deduct 693 from 730 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final result is 8792.37373737 with a remainder of 3.7e-08.
