Let's divide 57399668 by 109
The aim is to understand the frequency of 109 in 57399668.

Advancing to step 1:
When dividing 5 by 109, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 109

Step 2:
The number 109 fits into 57 0 times, leaving a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Grab the next digit (3) from the dividend, add it to 57, then carry on: 573 / 109

Moving on to step 3:
If we divide 573 by 109, we get 5 and a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 545 from 573 leaves us with 28.
Append the next digit (9) from the dividend to 28 and continue with: 289 / 109

On to step 4:
109 can be fit into 289 2 times, resulting in a remainder of 71.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Subtracting 218 from 289 leaves us with 71.
Grab the next digit (9) from the dividend, add it to 71, then carry on: 719 / 109

Moving on to step 5:
719 divided by 109 is 6 with a remainder of 65.
Use 6 as the next digit of our solution. 
Result so far: 526.0
The remainder is 65 after subtracting 654 from 719.
Include the next digit (6) from the dividend after 65, then repeat: 656 / 109

Going ahead to step 6:
The number 109 fits into 656 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 5266.0
If we take 654 away from 656, we end up with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 109

Step 7:
109 can be fit into 26 0 times, resulting in a remainder of 26.
The next digit of our result is 0. 
Result so far: 52660.0
Deduct 0 from 26 and we're left with 26.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 109

On to step 8:
268 divided by 109 is 2 with a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 526602.0
Deduct 218 from 268 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
500 divided by 109 is 4 with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 526602.4
The remainder is 64 after subtracting 436 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
When dividing 640 by 109, we get 5 with a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 526602.45
Subtract 545 from 640 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 11:
109 can be fit into 950 8 times, resulting in a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 526602.458
If we subtract 872 from 950, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 12:
If we divide 780 by 109, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 526602.4587
If we take 763 away from 780, we end up 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.

Let's proceed to step 13:
109 goes into 170 1 times with a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 526602.45871
Deduct 109 from 170 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 14:
If we divide 610 by 109, we get 5 and a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 526602.458715
If we take 545 away from 610, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 15:
109 can be fit into 650 5 times, resulting in a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 526602.4587155
Subtracting 545 from 650 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The quotient of the division is 526602.4587155, and the remainder is 1.05e-06.
