We're dividing 53700039 by 107 
The aim is to understand the frequency of 107 in 53700039.

Going ahead to step 1:
When dividing 5 by 107, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 107

Advancing to step 2:
107 goes into 53 0 times with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Grab the next digit (7) from the dividend, add it to 53, then carry on: 537 / 107

Advancing to step 3:
537 divided by 107 is 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 535 from 537, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 107

Advancing to step 4:
20 divided by 107 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 50.0
If we subtract 0 from 20, we get 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 107

Going ahead to step 5:
If we divide 200 by 107, we get 1 and a remainder of 93.
Put 1 as the next digit of the answer. 
Result so far: 501.0
Subtract 107 from 200 to get 93.
Fetch the next digit (0) from the dividend, attach it to 93 and continue: 930 / 107

Advancing to step 6:
107 goes into 930 8 times with a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 5018.0
The remainder is 74 after subtracting 856 from 930.
Grab the next digit (3) from the dividend, add it to 74, then carry on: 743 / 107

Advancing to step 7:
If we divide 743 by 107, we get 6 and a remainder of 101.
Record the quotient 6 as the next digit in the result. 
Result so far: 50186.0
Subtract 642 from 743 to get 101.
Take the next digit (9) from the dividend and append it to 101, then repeat: 1019 / 107

Advancing to step 8:
When dividing 1019 by 107, we get 9 with a remainder of 56.
Use 9 as the next digit of our solution. 
Result so far: 501869.0
If we take 963 away from 1019, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
107 can be fit into 560 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 501869.5
If we take 535 away from 560, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
250 divided by 107 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 501869.52
If we subtract 214 from 250, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
When dividing 360 by 107, we get 3 with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 501869.523
If we subtract 321 from 360, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 12:
When dividing 390 by 107, we get 3 with a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 501869.5233
If we subtract 321 from 390, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The quotient of the division is 501869.5233, and the remainder is 0.00069.
