Let's divide 752056 by 90
The aim is to understand the frequency of 90 in 752056.

On to step 1:
7 divided by 90 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 90

Going ahead to step 2:
75 divided by 90 is 0 with a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Fetch the next digit (2) from the dividend, attach it to 75 and continue: 752 / 90

On to step 3:
When dividing 752 by 90, we get 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 32 after subtracting 720 from 752.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 90

Let's proceed to step 4:
The number 90 fits into 320 3 times, leaving a remainder of 50.
The next digit of our result is 3. 
Result so far: 83.0
If we take 270 away from 320, we end up with 50.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 90

Going ahead to step 5:
If we divide 505 by 90, we get 5 and a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 835.0
If we subtract 450 from 505, we get 55.
Append the next digit (6) from the dividend to 55 and continue with: 556 / 90

On to step 6:
90 can be fit into 556 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 8356.0
If we take 540 away from 556, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
90 goes into 160 1 times with a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 8356.1
Subtract 90 from 160 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
90 goes into 700 7 times with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 8356.17
The remainder is 70 after subtracting 630 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
The number 90 fits into 700 7 times, leaving a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 8356.177
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 8356.177 with a remaining 0.007.
