196741 ÷ 90 
The aim is to understand the frequency of 90 in 196741.

Step 1:
The number 90 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 90

Step 2:
90 can be fit into 19 0 times, resulting in a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 90

Advancing to step 3:
If we divide 196 by 90, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 180 from 196, we get 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 90

Moving on to step 4:
167 divided by 90 is 1 with a remainder of 77.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 90 from 167 leaves us with 77.
Grab the next digit (4) from the dividend, add it to 77, then carry on: 774 / 90

Step 5:
774 divided by 90 is 8 with a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 218.0
The remainder is 54 after subtracting 720 from 774.
Fetch the next digit (1) from the dividend, attach it to 54 and continue: 541 / 90

Advancing to step 6:
90 can be fit into 541 6 times, resulting in a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 2186.0
Subtracting 540 from 541 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
When dividing 10 by 90, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 2186.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
90 can be fit into 100 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 2186.01
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
90 can be fit into 100 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 2186.011
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 2186.011, and the remainder is 0.001.
