76252946 divided by 621 
The aim is to understand the frequency of 621 in 76252946.

Moving on to step 1:
The number 621 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 621

Moving on to step 2:
When dividing 76 by 621, we get 0 with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Bring next digit (2) of the dividend behind the 76 and repeat the process: 762 / 621

Moving on to step 3:
621 goes into 762 1 times with a remainder of 141.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 621 away from 762, we end up with 141.
Take the next digit (5) from the dividend and append it to 141, then repeat: 1415 / 621

Going ahead to step 4:
621 goes into 1415 2 times with a remainder of 173.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 1242 from 1415 leaves us with 173.
Append the next digit (2) from the dividend to 173 and continue with: 1732 / 621

Step 5:
621 goes into 1732 2 times with a remainder of 490.
Use 2 as the next digit of our solution. 
Result so far: 122.0
The remainder is 490 after subtracting 1242 from 1732.
Fetch the next digit (9) from the dividend, attach it to 490 and continue: 4909 / 621

Going ahead to step 6:
When dividing 4909 by 621, we get 7 with a remainder of 562.
Use 7 as the next digit of our solution. 
Result so far: 1227.0
The remainder is 562 after subtracting 4347 from 4909.
Include the next digit (4) from the dividend after 562, then repeat: 5624 / 621

On to step 7:
5624 divided by 621 is 9 with a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 12279.0
If we subtract 5589 from 5624, we get 35.
Fetch the next digit (6) from the dividend, attach it to 35 and continue: 356 / 621

On to step 8:
621 goes into 356 0 times with a remainder of 356.
Record the quotient 0 as the next digit in the result. 
Result so far: 122790.0
If we subtract 0 from 356, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 9:
3560 divided by 621 is 5 with a remainder of 455.
Use 5 as the next digit of our solution. 
Result so far: 122790.5
The remainder is 455 after subtracting 3105 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Advancing to step 10:
621 goes into 4550 7 times with a remainder of 203.
Record the quotient 7 as the next digit in the result. 
Result so far: 122790.57
Subtract 4347 from 4550 to get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 11:
621 goes into 2030 3 times with a remainder of 167.
The number 3 becomes the next digit in our result. 
Result so far: 122790.573
Subtracting 1863 from 2030 leaves us with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Step 12:
621 goes into 1670 2 times with a remainder of 428.
The next digit of our result is 2. 
Result so far: 122790.5732
Subtract 1242 from 1670 to get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 13:
If we divide 4280 by 621, we get 6 and a remainder of 554.
The next digit of our result is 6. 
Result so far: 122790.57326
The remainder is 554 after subtracting 3726 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Advancing to step 14:
When dividing 5540 by 621, we get 8 with a remainder of 572.
Use 8 as the next digit of our solution. 
Result so far: 122790.573268
Subtract 4968 from 5540 to get 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

On to step 15:
If we divide 5720 by 621, we get 9 and a remainder of 131.
Put 9 as the next digit of the answer. 
Result so far: 122790.5732689
If we subtract 5589 from 5720, we get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Going ahead to step 16:
When dividing 1310 by 621, we get 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 122790.57326892
Deduct 1242 from 1310 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 122790.57326892, with a leftover of 6.8e-08.
