We look at the division of 91341095 by 57 
The aim is to understand the frequency of 57 in 91341095.

Moving on to step 1:
9 divided by 57 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 57

Let's proceed to step 2:
The number 57 fits into 91 1 times, leaving a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 57 from 91 leaves us with 34.
Take the next digit (3) from the dividend and append it to 34, then repeat: 343 / 57

Moving on to step 3:
57 can be fit into 343 6 times, resulting in a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 342 from 343 to get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 57

Let's proceed to step 4:
When dividing 14 by 57, we get 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
If we subtract 0 from 14, we get 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 57

Moving on to step 5:
When dividing 141 by 57, we get 2 with a remainder of 27.
Record the quotient 2 as the next digit in the result. 
Result so far: 1602.0
The remainder is 27 after subtracting 114 from 141.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 57

Step 6:
If we divide 270 by 57, we get 4 and a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 16024.0
If we subtract 228 from 270, we get 42.
Fetch the next digit (9) from the dividend, attach it to 42 and continue: 429 / 57

Let's proceed to step 7:
When dividing 429 by 57, we get 7 with a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 160247.0
Subtract 399 from 429 to get 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 57

Moving on to step 8:
The number 57 fits into 305 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 1602475.0
Subtract 285 from 305 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
57 can be fit into 200 3 times, resulting in a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 1602475.3
Subtract 171 from 200 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 10:
290 divided by 57 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1602475.35
Subtracting 285 from 290 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
When dividing 50 by 57, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 1602475.35
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
If we divide 500 by 57, we get 8 and a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 1602475.3508
Subtract 456 from 500 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
57 goes into 440 7 times with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 1602475.35087
Subtracting 399 from 440 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 14:
The number 57 fits into 410 7 times, leaving a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 1602475.350877
Subtract 399 from 410 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 1602475.350877, with a leftover of 1.1e-06.
