We're dividing 90993330 by 970 
The aim is to understand the frequency of 970 in 90993330.

Advancing to step 1:
When dividing 9 by 970, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 970

Step 2:
The number 970 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Append the next digit (9) from the dividend to 90 and continue with: 909 / 970

Advancing to step 3:
909 divided by 970 is 0 with a remainder of 909.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 909, we end up with 909.
Fetch the next digit (9) from the dividend, attach it to 909 and continue: 9099 / 970

Going ahead to step 4:
9099 divided by 970 is 9 with a remainder of 369.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 8730 away from 9099, we end up with 369.
Grab the next digit (3) from the dividend, add it to 369, then carry on: 3693 / 970

Going ahead to step 5:
The number 970 fits into 3693 3 times, leaving a remainder of 783.
Put 3 as the next digit of the answer. 
Result so far: 93.0
Subtract 2910 from 3693 to get 783.
Take the next digit (3) from the dividend and append it to 783, then repeat: 7833 / 970

On to step 6:
970 goes into 7833 8 times with a remainder of 73.
Use 8 as the next digit of our solution. 
Result so far: 938.0
If we take 7760 away from 7833, we end up with 73.
Take the next digit (3) from the dividend and append it to 73, then repeat: 733 / 970

Advancing to step 7:
733 divided by 970 is 0 with a remainder of 733.
Use 0 as the next digit of our solution. 
Result so far: 9380.0
Subtract 0 from 733 to get 733.
Fetch the next digit (0) from the dividend, attach it to 733 and continue: 7330 / 970

On to step 8:
970 goes into 7330 7 times with a remainder of 540.
Write down 7 as next digit of the result. 
Result so far: 93807.0
If we subtract 6790 from 7330, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 9:
When dividing 5400 by 970, we get 5 with a remainder of 550.
The next digit of our result is 5. 
Result so far: 93807.5
If we subtract 4850 from 5400, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 10:
5500 divided by 970 is 5 with a remainder of 650.
Record the quotient 5 as the next digit in the result. 
Result so far: 93807.55
If we subtract 4850 from 5500, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

The quotient of the division is 93807.55, and the remainder is 0.65.
