We look at the division of 91157349 by 712 
The aim is to understand the frequency of 712 in 91157349.

Going ahead to step 1:
712 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 712

On to step 2:
712 can be fit into 91 0 times, resulting in a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Fetch the next digit (1) from the dividend, attach it to 91 and continue: 911 / 712

Moving on to step 3:
The number 712 fits into 911 1 times, leaving a remainder of 199.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 712 from 911 leaves us with 199.
Append the next digit (5) from the dividend to 199 and continue with: 1995 / 712

On to step 4:
When dividing 1995 by 712, we get 2 with a remainder of 571.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 1424 from 1995 and we're left with 571.
Fetch the next digit (7) from the dividend, attach it to 571 and continue: 5717 / 712

Advancing to step 5:
If we divide 5717 by 712, we get 8 and a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Subtracting 5696 from 5717 leaves us with 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 712

Going ahead to step 6:
If we divide 213 by 712, we get 0 and a remainder of 213.
The next digit of our result is 0. 
Result so far: 1280.0
If we subtract 0 from 213, we get 213.
Fetch the next digit (4) from the dividend, attach it to 213 and continue: 2134 / 712

Advancing to step 7:
2134 divided by 712 is 2 with a remainder of 710.
The next digit of our result is 2. 
Result so far: 12802.0
Deduct 1424 from 2134 and we're left with 710.
Take the next digit (9) from the dividend and append it to 710, then repeat: 7109 / 712

Advancing to step 8:
If we divide 7109 by 712, we get 9 and a remainder of 701.
The next digit of our result is 9. 
Result so far: 128029.0
Deduct 6408 from 7109 and we're left with 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

Advancing to step 9:
7010 divided by 712 is 9 with a remainder of 602.
Use 9 as the next digit of our solution. 
Result so far: 128029.9
Deduct 6408 from 7010 and we're left with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Going ahead to step 10:
If we divide 6020 by 712, we get 8 and a remainder of 324.
The number 8 becomes the next digit in our result. 
Result so far: 128029.98
Deduct 5696 from 6020 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 11:
If we divide 3240 by 712, we get 4 and a remainder of 392.
Use 4 as the next digit of our solution. 
Result so far: 128029.984
Deduct 2848 from 3240 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 12:
The number 712 fits into 3920 5 times, leaving a remainder of 360.
Record the quotient 5 as the next digit in the result. 
Result so far: 128029.9845
Deduct 3560 from 3920 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 13:
712 goes into 3600 5 times with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 128029.98455
Deduct 3560 from 3600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 128029.98455 and a remainder of 4e-05.
