Let's divide 84143911 by 261
The aim is to understand the frequency of 261 in 84143911.

Advancing to step 1:
The number 261 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 261

Advancing to step 2:
84 divided by 261 is 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Take the next digit (1) from the dividend and append it to 84, then repeat: 841 / 261

On to step 3:
The number 261 fits into 841 3 times, leaving a remainder of 58.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 58 after subtracting 783 from 841.
Bring next digit (4) of the dividend behind the 58 and repeat the process: 584 / 261

On to step 4:
261 can be fit into 584 2 times, resulting in a remainder of 62.
The next digit of our result is 2. 
Result so far: 32.0
Deduct 522 from 584 and we're left with 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 261

On to step 5:
The number 261 fits into 623 2 times, leaving a remainder of 101.
Put 2 as the next digit of the answer. 
Result so far: 322.0
The remainder is 101 after subtracting 522 from 623.
Append the next digit (9) from the dividend to 101 and continue with: 1019 / 261

Step 6:
When dividing 1019 by 261, we get 3 with a remainder of 236.
The number 3 becomes the next digit in our result. 
Result so far: 3223.0
Deduct 783 from 1019 and we're left with 236.
Grab the next digit (1) from the dividend, add it to 236, then carry on: 2361 / 261

Going ahead to step 7:
2361 divided by 261 is 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 32239.0
Deduct 2349 from 2361 and we're left with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 261

On to step 8:
If we divide 121 by 261, we get 0 and a remainder of 121.
Use 0 as the next digit of our solution. 
Result so far: 322390.0
Subtract 0 from 121 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 9:
261 can be fit into 1210 4 times, resulting in a remainder of 166.
The next digit of our result is 4. 
Result so far: 322390.4
Deduct 1044 from 1210 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 10:
If we divide 1660 by 261, we get 6 and a remainder of 94.
The number 6 becomes the next digit in our result. 
Result so far: 322390.46
Deduct 1566 from 1660 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 11:
940 divided by 261 is 3 with a remainder of 157.
The next digit of our result is 3. 
Result so far: 322390.463
The remainder is 157 after subtracting 783 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 12:
When dividing 1570 by 261, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 322390.4636
If we subtract 1566 from 1570, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
261 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 322390.4636
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
261 goes into 400 1 times with a remainder of 139.
Put 1 as the next digit of the answer. 
Result so far: 322390.463601
Subtracting 261 from 400 leaves us with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Moving on to step 15:
The number 261 fits into 1390 5 times, leaving a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 322390.4636015
If we take 1305 away from 1390, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 16:
850 divided by 261 is 3 with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 322390.46360153
If we subtract 783 from 850, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Our division results in 322390.46360153 with a remaining 6.7e-08.
