481594 divided by 91 
The aim is to understand the frequency of 91 in 481594.

Advancing to step 1:
91 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 91

On to step 2:
The number 91 fits into 48 0 times, leaving a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 48 to get 48.
Take the next digit (1) from the dividend and append it to 48, then repeat: 481 / 91

Step 3:
91 can be fit into 481 5 times, resulting in a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 26 after subtracting 455 from 481.
Append the next digit (5) from the dividend to 26 and continue with: 265 / 91

Going ahead to step 4:
When dividing 265 by 91, we get 2 with a remainder of 83.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Deduct 182 from 265 and we're left with 83.
Include the next digit (9) from the dividend after 83, then repeat: 839 / 91

On to step 5:
91 can be fit into 839 9 times, resulting in a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 529.0
If we take 819 away from 839, we end up with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 91

Step 6:
204 divided by 91 is 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 5292.0
Deduct 182 from 204 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
If we divide 220 by 91, we get 2 and a remainder of 38.
The next digit of our result is 2. 
Result so far: 5292.2
Subtract 182 from 220 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
91 can be fit into 380 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 5292.24
Deduct 364 from 380 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
When dividing 160 by 91, we get 1 with a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 5292.241
Subtracting 91 from 160 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 10:
91 can be fit into 690 7 times, resulting in a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 5292.2417
Deduct 637 from 690 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 11:
530 divided by 91 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 5292.24175
Subtracting 455 from 530 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 12:
If we divide 750 by 91, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 5292.241758
Deduct 728 from 750 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 13:
When dividing 220 by 91, we get 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 5292.2417582
If we subtract 182 from 220, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 14:
The number 91 fits into 380 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 5292.24175824
Subtract 364 from 380 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 5292.24175824 and a remainder of 1.6e-08.
