We're dividing 445610 by 91 
The aim is to understand the frequency of 91 in 445610.

Advancing to step 1:
4 divided by 91 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 91

Going ahead to step 2:
The number 91 fits into 44 0 times, leaving a remainder of 44.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 44, we end up with 44.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 91

Let's proceed to step 3:
445 divided by 91 is 4 with a remainder of 81.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 364 away from 445, we end up with 81.
Grab the next digit (6) from the dividend, add it to 81, then carry on: 816 / 91

Going ahead to step 4:
When dividing 816 by 91, we get 8 with a remainder of 88.
The next digit of our result is 8. 
Result so far: 48.0
If we subtract 728 from 816, we get 88.
Fetch the next digit (1) from the dividend, attach it to 88 and continue: 881 / 91

Step 5:
91 goes into 881 9 times with a remainder of 62.
Record the quotient 9 as the next digit in the result. 
Result so far: 489.0
Deduct 819 from 881 and we're left with 62.
Append the next digit (0) from the dividend to 62 and continue with: 620 / 91

Moving on to step 6:
When dividing 620 by 91, we get 6 with a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 4896.0
Subtracting 546 from 620 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 7:
The number 91 fits into 740 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 4896.8
Subtracting 728 from 740 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
91 can be fit into 120 1 times, resulting in a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 4896.81
If we take 91 away from 120, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 9:
91 goes into 290 3 times with a remainder of 17.
The next digit of our result is 3. 
Result so far: 4896.813
If we take 273 away from 290, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
The number 91 fits into 170 1 times, leaving a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 4896.8131
If we subtract 91 from 170, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 11:
The number 91 fits into 790 8 times, leaving a remainder of 62.
The next digit of our result is 8. 
Result so far: 4896.81318
The remainder is 62 after subtracting 728 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 12:
If we divide 620 by 91, we get 6 and a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 4896.813186
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 13:
If we divide 740 by 91, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 4896.8131868
Subtracting 728 from 740 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
When dividing 120 by 91, we get 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 4896.81318681
Subtract 91 from 120 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The quotient of the division is 4896.81318681, and the remainder is 2.9e-08.
