13947898 divided by 57 
The aim is to understand the frequency of 57 in 13947898.

Going ahead to step 1:
57 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 57

Moving on to step 2:
57 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 57

Let's proceed to step 3:
The number 57 fits into 139 2 times, leaving a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 114 away from 139, we end up with 25.
Grab the next digit (4) from the dividend, add it to 25, then carry on: 254 / 57

Advancing to step 4:
If we divide 254 by 57, we get 4 and a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we subtract 228 from 254, we get 26.
Append the next digit (7) from the dividend to 26 and continue with: 267 / 57

Step 5:
When dividing 267 by 57, we get 4 with a remainder of 39.
The next digit of our result is 4. 
Result so far: 244.0
Subtracting 228 from 267 leaves us with 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 57

Going ahead to step 6:
When dividing 398 by 57, we get 6 with a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 2446.0
If we take 342 away from 398, we end up with 56.
Bring next digit (9) of the dividend behind the 56 and repeat the process: 569 / 57

Moving on to step 7:
569 divided by 57 is 9 with a remainder of 56.
The number 9 becomes the next digit in our result. 
Result so far: 24469.0
If we take 513 away from 569, we end up with 56.
Fetch the next digit (8) from the dividend, attach it to 56 and continue: 568 / 57

Advancing to step 8:
The number 57 fits into 568 9 times, leaving a remainder of 55.
The next digit of our result is 9. 
Result so far: 244699.0
Deduct 513 from 568 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 9:
When dividing 550 by 57, we get 9 with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 244699.9
If we take 513 away from 550, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 10:
370 divided by 57 is 6 with a remainder of 28.
The next digit of our result is 6. 
Result so far: 244699.96
If we subtract 342 from 370, we 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:
The number 57 fits into 280 4 times, leaving a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 244699.964
If we subtract 228 from 280, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 12:
520 divided by 57 is 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 244699.9649
The remainder is 7 after subtracting 513 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 13:
The number 57 fits into 70 1 times, leaving a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 244699.96491
Subtracting 57 from 70 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 14:
57 goes into 130 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 244699.964912
If we subtract 114 from 130, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 15:
When dividing 160 by 57, we get 2 with a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 244699.9649122
Deduct 114 from 160 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 244699.9649122, with a leftover of 4.6e-07.
