We're dividing 681314 by 90 
The aim is to understand the frequency of 90 in 681314.

On to step 1:
90 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 90

Let's proceed to step 2:
90 goes into 68 0 times with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Include the next digit (1) from the dividend after 68, then repeat: 681 / 90

Moving on to step 3:
The number 90 fits into 681 7 times, leaving a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 630 from 681 to get 51.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 90

Going ahead to step 4:
90 can be fit into 513 5 times, resulting in a remainder of 63.
Use 5 as the next digit of our solution. 
Result so far: 75.0
Subtract 450 from 513 to get 63.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 90

On to step 5:
If we divide 631 by 90, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 757.0
The remainder is 1 after subtracting 630 from 631.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 90

Moving on to step 6:
The number 90 fits into 14 0 times, leaving a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 7570.0
The remainder is 14 after subtracting 0 from 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
140 divided by 90 is 1 with a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 7570.1
If we take 90 away from 140, we end up 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.

Let's proceed 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: 7570.15
The remainder is 50 after subtracting 450 from 500.
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:
When dividing 500 by 90, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 7570.155
Deduct 450 from 500 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.

The quotient of the division is 7570.155, and the remainder is 0.005.
