We divide 713448 by 90
The aim is to understand the frequency of 90 in 713448.

Let's proceed to step 1:
90 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 90

Let's proceed to step 2:
The number 90 fits into 71 0 times, leaving a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Include the next digit (3) from the dividend after 71, then repeat: 713 / 90

Step 3:
713 divided by 90 is 7 with a remainder of 83.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 630 from 713 leaves us with 83.
Bring next digit (4) of the dividend behind the 83 and repeat the process: 834 / 90

Step 4:
When dividing 834 by 90, we get 9 with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Deduct 810 from 834 and we're left with 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 90

Going ahead to step 5:
90 goes into 244 2 times with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 792.0
If we subtract 180 from 244, we get 64.
Append the next digit (8) from the dividend to 64 and continue with: 648 / 90

Going ahead to step 6:
648 divided by 90 is 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 7927.0
Subtracting 630 from 648 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
90 goes into 180 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 7927.2
If we subtract 180 from 180, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
If we divide 0 by 90, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 7927.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
90 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7927.2
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 7927.2, with a leftover of 0.0.
