Let's divide 41667198 by 621
The aim is to understand the frequency of 621 in 41667198.

Going ahead to step 1:
621 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 621

Going ahead to step 2:
If we divide 41 by 621, we get 0 and a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Bring next digit (6) of the dividend behind the 41 and repeat the process: 416 / 621

On to step 3:
416 divided by 621 is 0 with a remainder of 416.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 416 to get 416.
Grab the next digit (6) from the dividend, add it to 416, then carry on: 4166 / 621

Moving on to step 4:
The number 621 fits into 4166 6 times, leaving a remainder of 440.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 440 after subtracting 3726 from 4166.
Take the next digit (7) from the dividend and append it to 440, then repeat: 4407 / 621

Let's proceed to step 5:
621 can be fit into 4407 7 times, resulting in a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
Subtracting 4347 from 4407 leaves us with 60.
Bring next digit (1) of the dividend behind the 60 and repeat the process: 601 / 621

Going ahead to step 6:
621 can be fit into 601 0 times, resulting in a remainder of 601.
Use 0 as the next digit of our solution. 
Result so far: 670.0
If we subtract 0 from 601, we get 601.
Bring next digit (9) of the dividend behind the 601 and repeat the process: 6019 / 621

Moving on to step 7:
When dividing 6019 by 621, we get 9 with a remainder of 430.
Write down 9 as next digit of the result. 
Result so far: 6709.0
Subtract 5589 from 6019 to get 430.
Take the next digit (8) from the dividend and append it to 430, then repeat: 4308 / 621

Let's proceed to step 8:
621 can be fit into 4308 6 times, resulting in a remainder of 582.
Write down 6 as next digit of the result. 
Result so far: 67096.0
Subtract 3726 from 4308 to get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Let's proceed to step 9:
621 can be fit into 5820 9 times, resulting in a remainder of 231.
Put 9 as the next digit of the answer. 
Result so far: 67096.9
Subtracting 5589 from 5820 leaves us with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 10:
2310 divided by 621 is 3 with a remainder of 447.
Put 3 as the next digit of the answer. 
Result so far: 67096.93
Deduct 1863 from 2310 and we're left with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Going ahead to step 11:
4470 divided by 621 is 7 with a remainder of 123.
The next digit of our result is 7. 
Result so far: 67096.937
If we subtract 4347 from 4470, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 12:
When dividing 1230 by 621, we get 1 with a remainder of 609.
Write down 1 as next digit of the result. 
Result so far: 67096.9371
Deduct 621 from 1230 and we're left with 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Step 13:
The number 621 fits into 6090 9 times, leaving a remainder of 501.
The next digit of our result is 9. 
Result so far: 67096.93719
If we subtract 5589 from 6090, we get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Moving on to step 14:
621 goes into 5010 8 times with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 67096.937198
Subtracting 4968 from 5010 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 15:
621 can be fit into 420 0 times, resulting in a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 67096.937198
If we take 0 away from 420, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 16:
When dividing 4200 by 621, we get 6 with a remainder of 474.
The next digit of our result is 6. 
Result so far: 67096.93719806
Subtracting 3726 from 4200 leaves us with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

After the division, we end up with 67096.93719806 and a remainder of 4.74e-07.
