848583 ÷ 91 
The aim is to understand the frequency of 91 in 848583.

Moving on to step 1:
The number 91 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 91

Moving on to step 2:
91 can be fit into 84 0 times, resulting in a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Grab the next digit (8) from the dividend, add it to 84, then carry on: 848 / 91

Step 3:
848 divided by 91 is 9 with a remainder of 29.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 819 from 848, we get 29.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 91

Advancing to step 4:
When dividing 295 by 91, we get 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 93.0
Deduct 273 from 295 and we're left with 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 91

On to step 5:
91 can be fit into 228 2 times, resulting in a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 932.0
Subtracting 182 from 228 leaves us with 46.
Append the next digit (3) from the dividend to 46 and continue with: 463 / 91

Going ahead to step 6:
If we divide 463 by 91, we get 5 and a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 9325.0
If we take 455 away from 463, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
91 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 9325.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 8:
800 divided by 91 is 8 with a remainder of 72.
The next digit of our result is 8. 
Result so far: 9325.08
Subtracting 728 from 800 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 9:
When dividing 720 by 91, we get 7 with a remainder of 83.
The number 7 becomes the next digit in our result. 
Result so far: 9325.087
If we take 637 away from 720, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 10:
If we divide 830 by 91, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 9325.0879
Subtract 819 from 830 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
91 can be fit into 110 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 9325.08791
If we take 91 away from 110, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 12:
190 divided by 91 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 9325.087912
If we subtract 182 from 190, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
91 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 9325.087912
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 14:
91 goes into 800 8 times with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 9325.08791208
The remainder is 72 after subtracting 728 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 9325.08791208, and the remainder is 7.2e-08.
