We're dividing 60380714 by 91 
The aim is to understand the frequency of 91 in 60380714.

Step 1:
91 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 91

On to step 2:
60 divided by 91 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 60, we get 60.
Include the next digit (3) from the dividend after 60, then repeat: 603 / 91

On to step 3:
603 divided by 91 is 6 with a remainder of 57.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 57 after subtracting 546 from 603.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 91

Advancing to step 4:
91 goes into 578 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Subtracting 546 from 578 leaves us with 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 91

Going ahead to step 5:
If we divide 320 by 91, we get 3 and a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 663.0
If we subtract 273 from 320, we get 47.
Fetch the next digit (7) from the dividend, attach it to 47 and continue: 477 / 91

Let's proceed to step 6:
The number 91 fits into 477 5 times, leaving a remainder of 22.
Put 5 as the next digit of the answer. 
Result so far: 6635.0
If we subtract 455 from 477, we get 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 91

Step 7:
221 divided by 91 is 2 with a remainder of 39.
Put 2 as the next digit of the answer. 
Result so far: 66352.0
If we take 182 away from 221, we end up with 39.
Take the next digit (4) from the dividend and append it to 39, then repeat: 394 / 91

On to step 8:
When dividing 394 by 91, we get 4 with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 663524.0
If we subtract 364 from 394, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
The number 91 fits into 300 3 times, leaving a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 663524.3
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 10:
If we divide 270 by 91, we get 2 and a remainder of 88.
The next digit of our result is 2. 
Result so far: 663524.32
If we take 182 away from 270, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 11:
91 goes into 880 9 times with a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 663524.329
Subtract 819 from 880 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 12:
If we divide 610 by 91, we get 6 and a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 663524.3296
If we subtract 546 from 610, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
The number 91 fits into 640 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 663524.32967
The remainder is 3 after subtracting 637 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 14:
91 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 663524.32967
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 15:
91 can be fit into 300 3 times, resulting in a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 663524.3296703
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 16:
91 goes into 270 2 times with a remainder of 88.
Use 2 as the next digit of our solution. 
Result so far: 663524.32967032
If we take 182 away from 270, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

In conclusion, the division gives 663524.32967032 with a balance of 8.8e-08.
