We're dividing 157919 by 90 
The aim is to understand the frequency of 90 in 157919.

On to step 1:
90 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 90

On to step 2:
90 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 90

Let's proceed to step 3:
When dividing 157 by 90, we get 1 with a remainder of 67.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 90 from 157 leaves us with 67.
Append the next digit (9) from the dividend to 67 and continue with: 679 / 90

Advancing to step 4:
The number 90 fits into 679 7 times, leaving a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 630 from 679 and we're left with 49.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 90

On to step 5:
90 can be fit into 491 5 times, resulting in a remainder of 41.
Use 5 as the next digit of our solution. 
Result so far: 175.0
Deduct 450 from 491 and we're left with 41.
Fetch the next digit (9) from the dividend, attach it to 41 and continue: 419 / 90

Going ahead to step 6:
419 divided by 90 is 4 with a remainder of 59.
Put 4 as the next digit of the answer. 
Result so far: 1754.0
Subtract 360 from 419 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 7:
The number 90 fits into 590 6 times, leaving a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 1754.6
Deduct 540 from 590 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
If we divide 500 by 90, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 1754.65
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
500 divided by 90 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1754.655
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 1754.655 with a balance of 0.005.
