We're dividing 316653 by 91 
The aim is to understand the frequency of 91 in 316653.

On to step 1:
When dividing 3 by 91, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 91

Step 2:
91 can be fit into 31 0 times, resulting in a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 91

On to step 3:
The number 91 fits into 316 3 times, leaving a remainder of 43.
The next digit of our result is 3. 
Result so far: 3.0
If we take 273 away from 316, we end up with 43.
Append the next digit (6) from the dividend to 43 and continue with: 436 / 91

Step 4:
91 can be fit into 436 4 times, resulting in a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 34.0
The remainder is 72 after subtracting 364 from 436.
Fetch the next digit (5) from the dividend, attach it to 72 and continue: 725 / 91

Going ahead to step 5:
When dividing 725 by 91, we get 7 with a remainder of 88.
The next digit of our result is 7. 
Result so far: 347.0
If we subtract 637 from 725, we get 88.
Append the next digit (3) from the dividend to 88 and continue with: 883 / 91

On to step 6:
When dividing 883 by 91, we get 9 with a remainder of 64.
The next digit of our result is 9. 
Result so far: 3479.0
The remainder is 64 after subtracting 819 from 883.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 7:
91 goes into 640 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 3479.7
Subtracting 637 from 640 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
When dividing 30 by 91, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 3479.7
The remainder is 30 after subtracting 0 from 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 9:
91 goes into 300 3 times with a remainder of 27.
The next digit of our result is 3. 
Result so far: 3479.703
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.

Going ahead to step 10:
91 goes into 270 2 times with a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 3479.7032
Subtracting 182 from 270 leaves us 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.

Step 11:
When dividing 880 by 91, we get 9 with a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 3479.70329
If we take 819 away from 880, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 12:
91 goes into 610 6 times with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 3479.703296
Deduct 546 from 610 and we're left with 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:
91 can be fit into 640 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 3479.7032967
If we take 637 away from 640, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 14:
30 divided by 91 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 3479.7032967
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.

The final result is 3479.7032967 with a remainder of 3e-08.
