920349 divided by 90 
The aim is to understand the frequency of 90 in 920349.

Advancing to step 1:
90 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 90

Step 2:
If we divide 92 by 90, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 90 away from 92, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 90

Moving on to step 3:
When dividing 20 by 90, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 20 to get 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 90

Moving on to step 4:
90 can be fit into 203 2 times, resulting in a remainder of 23.
The next digit of our result is 2. 
Result so far: 102.0
If we subtract 180 from 203, we get 23.
Fetch the next digit (4) from the dividend, attach it to 23 and continue: 234 / 90

Advancing to step 5:
If we divide 234 by 90, we get 2 and a remainder of 54.
The next digit of our result is 2. 
Result so far: 1022.0
Subtract 180 from 234 to get 54.
Fetch the next digit (9) from the dividend, attach it to 54 and continue: 549 / 90

Step 6:
If we divide 549 by 90, we get 6 and a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 10226.0
The remainder is 9 after subtracting 540 from 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
90 can be fit into 90 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 10226.1
If we subtract 90 from 90, 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.

Going ahead to step 8:
90 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10226.1
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 90 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10226.1
Deduct 0 from 0 and we're left 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.

Our division results in 10226.1 with a remaining 0.0.
