1944177 divided by 90 
The aim is to understand the frequency of 90 in 1944177.

Step 1:
90 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 90

Moving on to step 2:
90 goes into 19 0 times with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 90

Advancing to step 3:
90 can be fit into 194 2 times, resulting in a remainder of 14.
The next digit of our result is 2. 
Result so far: 2.0
If we take 180 away from 194, we end up with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 90

Step 4:
90 goes into 144 1 times with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 90 from 144, we get 54.
Grab the next digit (1) from the dividend, add it to 54, then carry on: 541 / 90

Step 5:
90 goes into 541 6 times with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 216.0
If we take 540 away from 541, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 90

On to step 6:
The number 90 fits into 17 0 times, leaving a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 2160.0
Deduct 0 from 17 and we're left with 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 90

Advancing to step 7:
90 can be fit into 177 1 times, resulting in a remainder of 87.
The next digit of our result is 1. 
Result so far: 21601.0
If we subtract 90 from 177, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 8:
If we divide 870 by 90, we get 9 and a remainder of 60.
Record the quotient 9 as the next digit in the result. 
Result so far: 21601.9
Subtracting 810 from 870 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
When dividing 600 by 90, we get 6 with a remainder of 60.
The next digit of our result is 6. 
Result so far: 21601.96
Subtracting 540 from 600 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
90 can be fit into 600 6 times, resulting in a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 21601.966
Subtract 540 from 600 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 21601.966, with a leftover of 0.006.
