42390883 ÷ 44 
The aim is to understand the frequency of 44 in 42390883.

Moving on to step 1:
4 divided by 44 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 44

Advancing to step 2:
If we divide 42 by 44, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 44

Step 3:
423 divided by 44 is 9 with a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 396 from 423, we get 27.
Append the next digit (9) from the dividend to 27 and continue with: 279 / 44

Moving on to step 4:
44 goes into 279 6 times with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
The remainder is 15 after subtracting 264 from 279.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 44

Let's proceed to step 5:
The number 44 fits into 150 3 times, leaving a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 963.0
If we take 132 away from 150, we end up with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 44

Moving on to step 6:
The number 44 fits into 188 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 9634.0
Subtract 176 from 188 to get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 44

On to step 7:
When dividing 128 by 44, we get 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 96342.0
If we take 88 away from 128, we end up with 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 44

Let's proceed to step 8:
If we divide 403 by 44, we get 9 and a remainder of 7.
The next digit of our result is 9. 
Result so far: 963429.0
Subtract 396 from 403 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
If we divide 70 by 44, we get 1 and a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 963429.1
Deduct 44 from 70 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
If we divide 260 by 44, we get 5 and a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 963429.15
Subtracting 220 from 260 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
400 divided by 44 is 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 963429.159
Subtracting 396 from 400 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
44 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 963429.159
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
44 goes into 400 9 times with a remainder of 4.
The next digit of our result is 9. 
Result so far: 963429.15909
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
If we divide 40 by 44, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 963429.15909
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 15:
When dividing 400 by 44, we get 9 with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 963429.1590909
Subtract 396 from 400 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 16:
40 divided by 44 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 963429.1590909
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 963429.1590909 and a remainder of 4e-08.
