99717191 divided by 989 
The aim is to understand the frequency of 989 in 99717191.

On to step 1:
The number 989 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 989

Let's proceed to step 2:
When dividing 99 by 989, we get 0 with a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Bring next digit (7) of the dividend behind the 99 and repeat the process: 997 / 989

Step 3:
The number 989 fits into 997 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 989 from 997 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 989

Step 4:
989 can be fit into 81 0 times, resulting in a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 81 after subtracting 0 from 81.
Take the next digit (7) from the dividend and append it to 81, then repeat: 817 / 989

Let's proceed to step 5:
989 goes into 817 0 times with a remainder of 817.
Write down 0 as next digit of the result. 
Result so far: 100.0
Deduct 0 from 817 and we're left with 817.
Fetch the next digit (1) from the dividend, attach it to 817 and continue: 8171 / 989

Advancing to step 6:
989 goes into 8171 8 times with a remainder of 259.
The next digit of our result is 8. 
Result so far: 1008.0
Subtract 7912 from 8171 to get 259.
Fetch the next digit (9) from the dividend, attach it to 259 and continue: 2599 / 989

Going ahead to step 7:
When dividing 2599 by 989, we get 2 with a remainder of 621.
Write down 2 as next digit of the result. 
Result so far: 10082.0
If we subtract 1978 from 2599, we get 621.
Take the next digit (1) from the dividend and append it to 621, then repeat: 6211 / 989

Let's proceed to step 8:
The number 989 fits into 6211 6 times, leaving a remainder of 277.
Record the quotient 6 as the next digit in the result. 
Result so far: 100826.0
If we subtract 5934 from 6211, we get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Advancing to step 9:
989 can be fit into 2770 2 times, resulting in a remainder of 792.
Put 2 as the next digit of the answer. 
Result so far: 100826.2
The remainder is 792 after subtracting 1978 from 2770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Going ahead to step 10:
989 goes into 7920 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 100826.28
If we take 7912 away from 7920, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
80 divided by 989 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 100826.28
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
The number 989 fits into 800 0 times, leaving a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 100826.28
If we subtract 0 from 800, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The quotient of the division is 100826.28, and the remainder is 0.008.
