Let's divide 90871829 by 841
The aim is to understand the frequency of 841 in 90871829.

On to step 1:
When dividing 9 by 841, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 841

Going ahead to step 2:
When dividing 90 by 841, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Fetch the next digit (8) from the dividend, attach it to 90 and continue: 908 / 841

Let's proceed to step 3:
The number 841 fits into 908 1 times, leaving a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 841 from 908, we get 67.
Append the next digit (7) from the dividend to 67 and continue with: 677 / 841

Let's proceed to step 4:
The number 841 fits into 677 0 times, leaving a remainder of 677.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 677 and we're left with 677.
Grab the next digit (1) from the dividend, add it to 677, then carry on: 6771 / 841

Moving on to step 5:
The number 841 fits into 6771 8 times, leaving a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 108.0
Deduct 6728 from 6771 and we're left with 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 841

Moving on to step 6:
If we divide 438 by 841, we get 0 and a remainder of 438.
Record the quotient 0 as the next digit in the result. 
Result so far: 1080.0
If we subtract 0 from 438, we get 438.
Fetch the next digit (2) from the dividend, attach it to 438 and continue: 4382 / 841

Step 7:
4382 divided by 841 is 5 with a remainder of 177.
Use 5 as the next digit of our solution. 
Result so far: 10805.0
Subtract 4205 from 4382 to get 177.
Take the next digit (9) from the dividend and append it to 177, then repeat: 1779 / 841

Step 8:
The number 841 fits into 1779 2 times, leaving a remainder of 97.
Write down 2 as next digit of the result. 
Result so far: 108052.0
Subtract 1682 from 1779 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 9:
When dividing 970 by 841, we get 1 with a remainder of 129.
Write down 1 as next digit of the result. 
Result so far: 108052.1
Subtracting 841 from 970 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 10:
841 can be fit into 1290 1 times, resulting in a remainder of 449.
Record the quotient 1 as the next digit in the result. 
Result so far: 108052.11
Subtracting 841 from 1290 leaves us with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

The final result is 108052.11 with a remainder of 0.449.
