714396 divided by 90 
The aim is to understand the frequency of 90 in 714396.

On to step 1:
If we divide 7 by 90, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 90

Advancing to step 2:
90 can be fit into 71 0 times, resulting in a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Grab the next digit (4) from the dividend, add it to 71, then carry on: 714 / 90

Advancing to step 3:
If we divide 714 by 90, we get 7 and a remainder of 84.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 84 after subtracting 630 from 714.
Grab the next digit (3) from the dividend, add it to 84, then carry on: 843 / 90

Moving on to step 4:
843 divided by 90 is 9 with a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 79.0
Subtract 810 from 843 to get 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 90

On to step 5:
90 goes into 339 3 times with a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 793.0
Deduct 270 from 339 and we're left with 69.
Take the next digit (6) from the dividend and append it to 69, then repeat: 696 / 90

Let's proceed to step 6:
When dividing 696 by 90, we get 7 with a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 7937.0
Deduct 630 from 696 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 7:
The number 90 fits into 660 7 times, leaving a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 7937.7
Deduct 630 from 660 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
300 divided by 90 is 3 with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 7937.73
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
90 goes into 300 3 times with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 7937.733
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 7937.733 with a balance of 0.003.
