Let's divide 442005 by 91
The aim is to understand the frequency of 91 in 442005.

Moving on to step 1:
The number 91 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 91

Going ahead to step 2:
91 goes into 44 0 times with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 44, we get 44.
Include the next digit (2) from the dividend after 44, then repeat: 442 / 91

Moving on to step 3:
91 goes into 442 4 times with a remainder of 78.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 78 after subtracting 364 from 442.
Include the next digit (0) from the dividend after 78, then repeat: 780 / 91

Advancing to step 4:
The number 91 fits into 780 8 times, leaving a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Deduct 728 from 780 and we're left with 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 91

Advancing to step 5:
91 can be fit into 520 5 times, resulting in a remainder of 65.
The next digit of our result is 5. 
Result so far: 485.0
If we take 455 away from 520, we end up with 65.
Bring next digit (5) of the dividend behind the 65 and repeat the process: 655 / 91

Moving on to step 6:
655 divided by 91 is 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 4857.0
The remainder is 18 after subtracting 637 from 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
When dividing 180 by 91, we get 1 with a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 4857.1
If we take 91 away from 180, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 8:
91 can be fit into 890 9 times, resulting in a remainder of 71.
The next digit of our result is 9. 
Result so far: 4857.19
If we subtract 819 from 890, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 9:
91 can be fit into 710 7 times, resulting in a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 4857.197
If we take 637 away from 710, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 10:
91 can be fit into 730 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 4857.1978
Subtracting 728 from 730 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
20 divided by 91 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4857.1978
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
When dividing 200 by 91, we get 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 4857.197802
If we take 182 away from 200, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
91 can be fit into 180 1 times, resulting in a remainder of 89.
Use 1 as the next digit of our solution. 
Result so far: 4857.1978021
Deduct 91 from 180 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 14:
91 goes into 890 9 times with a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 4857.19780219
If we take 819 away from 890, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The quotient of the division is 4857.19780219, and the remainder is 7.1e-08.
