We divide 75342111 by 91
The aim is to understand the frequency of 91 in 75342111.

On to step 1:
The number 91 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 91

On to step 2:
When dividing 75 by 91, we get 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Grab the next digit (3) from the dividend, add it to 75, then carry on: 753 / 91

Advancing to step 3:
91 can be fit into 753 8 times, resulting in a remainder of 25.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 25 after subtracting 728 from 753.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 91

Let's proceed to step 4:
The number 91 fits into 254 2 times, leaving a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we subtract 182 from 254, we get 72.
Append the next digit (2) from the dividend to 72 and continue with: 722 / 91

Step 5:
91 goes into 722 7 times with a remainder of 85.
Put 7 as the next digit of the answer. 
Result so far: 827.0
Deduct 637 from 722 and we're left with 85.
Grab the next digit (1) from the dividend, add it to 85, then carry on: 851 / 91

Going ahead to step 6:
When dividing 851 by 91, we get 9 with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 8279.0
Subtract 819 from 851 to get 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 91

Moving on to step 7:
If we divide 321 by 91, we get 3 and a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 82793.0
If we subtract 273 from 321, we get 48.
Take the next digit (1) from the dividend and append it to 48, then repeat: 481 / 91

Going ahead to step 8:
91 goes into 481 5 times with a remainder of 26.
The next digit of our result is 5. 
Result so far: 827935.0
If we subtract 455 from 481, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
The number 91 fits into 260 2 times, leaving a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 827935.2
Subtract 182 from 260 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 10:
91 can be fit into 780 8 times, resulting in a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 827935.28
Subtract 728 from 780 to 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.

Let's proceed to step 11:
91 can be fit into 520 5 times, resulting in a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 827935.285
If we subtract 455 from 520, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 12:
91 goes into 650 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 827935.2857
Subtracting 637 from 650 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.

Advancing to step 13:
When dividing 130 by 91, we get 1 with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 827935.28571
The remainder is 39 after subtracting 91 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 14:
The number 91 fits into 390 4 times, leaving a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 827935.285714
The remainder is 26 after subtracting 364 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 15:
91 goes into 260 2 times with a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 827935.2857142
If we subtract 182 from 260, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 16:
If we divide 780 by 91, we get 8 and a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 827935.28571428
If we subtract 728 from 780, 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.

The final result is 827935.28571428 with a remainder of 5.2e-08.
