Let's divide 62666103 by 921
The aim is to understand the frequency of 921 in 62666103.

Step 1:
6 divided by 921 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 921

Moving on to step 2:
The number 921 fits into 62 0 times, leaving a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Take the next digit (6) from the dividend and append it to 62, then repeat: 626 / 921

Going ahead to step 3:
The number 921 fits into 626 0 times, leaving a remainder of 626.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 626 leaves us with 626.
Take the next digit (6) from the dividend and append it to 626, then repeat: 6266 / 921

Moving on to step 4:
If we divide 6266 by 921, we get 6 and a remainder of 740.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 740 after subtracting 5526 from 6266.
Append the next digit (6) from the dividend to 740 and continue with: 7406 / 921

On to step 5:
921 goes into 7406 8 times with a remainder of 38.
The next digit of our result is 8. 
Result so far: 68.0
Subtracting 7368 from 7406 leaves us with 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 921

Moving on to step 6:
If we divide 381 by 921, we get 0 and a remainder of 381.
Use 0 as the next digit of our solution. 
Result so far: 680.0
Subtract 0 from 381 to get 381.
Include the next digit (0) from the dividend after 381, then repeat: 3810 / 921

Step 7:
921 goes into 3810 4 times with a remainder of 126.
Use 4 as the next digit of our solution. 
Result so far: 6804.0
If we take 3684 away from 3810, we end up with 126.
Take the next digit (3) from the dividend and append it to 126, then repeat: 1263 / 921

On to step 8:
If we divide 1263 by 921, we get 1 and a remainder of 342.
Use 1 as the next digit of our solution. 
Result so far: 68041.0
Subtracting 921 from 1263 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 9:
If we divide 3420 by 921, we get 3 and a remainder of 657.
Write down 3 as next digit of the result. 
Result so far: 68041.3
The remainder is 657 after subtracting 2763 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Step 10:
If we divide 6570 by 921, we get 7 and a remainder of 123.
Write down 7 as next digit of the result. 
Result so far: 68041.37
The remainder is 123 after subtracting 6447 from 6570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 11:
The number 921 fits into 1230 1 times, leaving a remainder of 309.
Put 1 as the next digit of the answer. 
Result so far: 68041.371
Subtract 921 from 1230 to get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Going ahead to step 12:
The number 921 fits into 3090 3 times, leaving a remainder of 327.
Use 3 as the next digit of our solution. 
Result so far: 68041.3713
If we take 2763 away from 3090, we end up with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

On to step 13:
921 goes into 3270 3 times with a remainder of 507.
Write down 3 as next digit of the result. 
Result so far: 68041.37133
Subtract 2763 from 3270 to get 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

The final outcome is 68041.37133, with a leftover of 0.000507.
