83663918 divided by 841 
The aim is to understand the frequency of 841 in 83663918.

On to step 1:
If we divide 8 by 841, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 841

Advancing to step 2:
841 can be fit into 83 0 times, resulting in a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Include the next digit (6) from the dividend after 83, then repeat: 836 / 841

Let's proceed to step 3:
When dividing 836 by 841, we get 0 with a remainder of 836.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 836 to get 836.
Bring next digit (6) of the dividend behind the 836 and repeat the process: 8366 / 841

Going ahead to step 4:
8366 divided by 841 is 9 with a remainder of 797.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 7569 from 8366 leaves us with 797.
Take the next digit (3) from the dividend and append it to 797, then repeat: 7973 / 841

On to step 5:
841 can be fit into 7973 9 times, resulting in a remainder of 404.
Write down 9 as next digit of the result. 
Result so far: 99.0
If we subtract 7569 from 7973, we get 404.
Append the next digit (9) from the dividend to 404 and continue with: 4049 / 841

Moving on to step 6:
The number 841 fits into 4049 4 times, leaving a remainder of 685.
The number 4 becomes the next digit in our result. 
Result so far: 994.0
The remainder is 685 after subtracting 3364 from 4049.
Append the next digit (1) from the dividend to 685 and continue with: 6851 / 841

Step 7:
841 goes into 6851 8 times with a remainder of 123.
Use 8 as the next digit of our solution. 
Result so far: 9948.0
Subtract 6728 from 6851 to get 123.
Take the next digit (8) from the dividend and append it to 123, then repeat: 1238 / 841

On to step 8:
If we divide 1238 by 841, we get 1 and a remainder of 397.
The number 1 becomes the next digit in our result. 
Result so far: 99481.0
If we take 841 away from 1238, we end up with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Moving on to step 9:
3970 divided by 841 is 4 with a remainder of 606.
The number 4 becomes the next digit in our result. 
Result so far: 99481.4
If we subtract 3364 from 3970, we get 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Let's proceed to step 10:
The number 841 fits into 6060 7 times, leaving a remainder of 173.
Record the quotient 7 as the next digit in the result. 
Result so far: 99481.47
Subtract 5887 from 6060 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Let's proceed to step 11:
If we divide 1730 by 841, we get 2 and a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 99481.472
Subtracting 1682 from 1730 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
When dividing 480 by 841, we get 0 with a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 99481.472
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 13:
841 can be fit into 4800 5 times, resulting in a remainder of 595.
The number 5 becomes the next digit in our result. 
Result so far: 99481.47205
Subtracting 4205 from 4800 leaves us with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Step 14:
841 can be fit into 5950 7 times, resulting in a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 99481.472057
If we subtract 5887 from 5950, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 15:
841 goes into 630 0 times with a remainder of 630.
Use 0 as the next digit of our solution. 
Result so far: 99481.472057
Subtract 0 from 630 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 16:
When dividing 6300 by 841, we get 7 with a remainder of 413.
The number 7 becomes the next digit in our result. 
Result so far: 99481.47205707
Deduct 5887 from 6300 and we're left with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

After the division, we end up with 99481.47205707 and a remainder of 4.13e-07.
