75185721 divided by 44 
The aim is to understand the frequency of 44 in 75185721.

Let's proceed to step 1:
When dividing 7 by 44, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 44

Going ahead to step 2:
44 can be fit into 75 1 times, resulting in a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 44 from 75, we get 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 44

Let's proceed to step 3:
If we divide 311 by 44, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 308 away from 311, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 44

Let's proceed to step 4:
The number 44 fits into 38 0 times, leaving a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 170.0
The remainder is 38 after subtracting 0 from 38.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 44

Step 5:
The number 44 fits into 385 8 times, leaving a remainder of 33.
Put 8 as the next digit of the answer. 
Result so far: 1708.0
If we subtract 352 from 385, we get 33.
Take the next digit (7) from the dividend and append it to 33, then repeat: 337 / 44

Moving on to step 6:
When dividing 337 by 44, we get 7 with a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 17087.0
If we take 308 away from 337, we end up with 29.
Fetch the next digit (2) from the dividend, attach it to 29 and continue: 292 / 44

Going ahead to step 7:
The number 44 fits into 292 6 times, leaving a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 170876.0
The remainder is 28 after subtracting 264 from 292.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 44

Step 8:
44 goes into 281 6 times with a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 1708766.0
Subtracting 264 from 281 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 9:
When dividing 170 by 44, we get 3 with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 1708766.3
If we subtract 132 from 170, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
44 goes into 380 8 times with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 1708766.38
Subtract 352 from 380 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
44 goes into 280 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 1708766.386
Deduct 264 from 280 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
If we divide 160 by 44, we get 3 and a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 1708766.3863
If we take 132 away from 160, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
44 goes into 280 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 1708766.38636
The remainder is 16 after subtracting 264 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
The number 44 fits into 160 3 times, leaving a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 1708766.386363
Subtract 132 from 160 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 15:
When dividing 280 by 44, we get 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 1708766.3863636
Subtracting 264 from 280 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 16:
44 can be fit into 160 3 times, resulting in a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 1708766.38636363
If we take 132 away from 160, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 1708766.38636363 with a remainder of 2.8e-08.
