Let's divide 68826923 by 621
The aim is to understand the frequency of 621 in 68826923.

Step 1:
621 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 621

Let's proceed to step 2:
The number 621 fits into 68 0 times, leaving a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Grab the next digit (8) from the dividend, add it to 68, then carry on: 688 / 621

Moving on to step 3:
621 goes into 688 1 times with a remainder of 67.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 621 from 688 to get 67.
Fetch the next digit (2) from the dividend, attach it to 67 and continue: 672 / 621

Going ahead to step 4:
The number 621 fits into 672 1 times, leaving a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 621 away from 672, we end up with 51.
Append the next digit (6) from the dividend to 51 and continue with: 516 / 621

Moving on to step 5:
When dividing 516 by 621, we get 0 with a remainder of 516.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
Subtracting 0 from 516 leaves us with 516.
Grab the next digit (9) from the dividend, add it to 516, then carry on: 5169 / 621

Moving on to step 6:
If we divide 5169 by 621, we get 8 and a remainder of 201.
The next digit of our result is 8. 
Result so far: 1108.0
Subtracting 4968 from 5169 leaves us with 201.
Grab the next digit (2) from the dividend, add it to 201, then carry on: 2012 / 621

Advancing to step 7:
621 can be fit into 2012 3 times, resulting in a remainder of 149.
Record the quotient 3 as the next digit in the result. 
Result so far: 11083.0
Subtracting 1863 from 2012 leaves us with 149.
Include the next digit (3) from the dividend after 149, then repeat: 1493 / 621

Moving on to step 8:
621 can be fit into 1493 2 times, resulting in a remainder of 251.
Put 2 as the next digit of the answer. 
Result so far: 110832.0
Subtracting 1242 from 1493 leaves us with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

On to step 9:
621 goes into 2510 4 times with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 110832.4
The remainder is 26 after subtracting 2484 from 2510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
When dividing 260 by 621, we get 0 with a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 110832.4
Subtract 0 from 260 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 11:
When dividing 2600 by 621, we get 4 with a remainder of 116.
Write down 4 as next digit of the result. 
Result so far: 110832.404
Subtracting 2484 from 2600 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 12:
621 can be fit into 1160 1 times, resulting in a remainder of 539.
Use 1 as the next digit of our solution. 
Result so far: 110832.4041
The remainder is 539 after subtracting 621 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Advancing to step 13:
If we divide 5390 by 621, we get 8 and a remainder of 422.
Record the quotient 8 as the next digit in the result. 
Result so far: 110832.40418
Subtract 4968 from 5390 to get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Step 14:
621 goes into 4220 6 times with a remainder of 494.
The number 6 becomes the next digit in our result. 
Result so far: 110832.404186
If we subtract 3726 from 4220, we get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Advancing to step 15:
When dividing 4940 by 621, we get 7 with a remainder of 593.
Write down 7 as next digit of the result. 
Result so far: 110832.4041867
If we take 4347 away from 4940, we end up with 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Moving on to step 16:
621 can be fit into 5930 9 times, resulting in a remainder of 341.
The next digit of our result is 9. 
Result so far: 110832.40418679
If we take 5589 away from 5930, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

The final result is 110832.40418679 with a remainder of 3.41e-07.
