Let's divide 39402220 by 681
The aim is to understand the frequency of 681 in 39402220.

Advancing to step 1:
681 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 681

On to step 2:
When dividing 39 by 681, we get 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 681

Going ahead to step 3:
If we divide 394 by 681, we get 0 and a remainder of 394.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 394, we get 394.
Append the next digit (0) from the dividend to 394 and continue with: 3940 / 681

Let's proceed to step 4:
When dividing 3940 by 681, we get 5 with a remainder of 535.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 535 after subtracting 3405 from 3940.
Include the next digit (2) from the dividend after 535, then repeat: 5352 / 681

Let's proceed to step 5:
5352 divided by 681 is 7 with a remainder of 585.
Write down 7 as next digit of the result. 
Result so far: 57.0
Subtract 4767 from 5352 to get 585.
Include the next digit (2) from the dividend after 585, then repeat: 5852 / 681

Moving on to step 6:
When dividing 5852 by 681, we get 8 with a remainder of 404.
The next digit of our result is 8. 
Result so far: 578.0
If we take 5448 away from 5852, we end up with 404.
Include the next digit (2) from the dividend after 404, then repeat: 4042 / 681

Moving on to step 7:
681 can be fit into 4042 5 times, resulting in a remainder of 637.
Put 5 as the next digit of the answer. 
Result so far: 5785.0
Subtracting 3405 from 4042 leaves us with 637.
Fetch the next digit (0) from the dividend, attach it to 637 and continue: 6370 / 681

On to step 8:
6370 divided by 681 is 9 with a remainder of 241.
Record the quotient 9 as the next digit in the result. 
Result so far: 57859.0
If we subtract 6129 from 6370, we get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

On to step 9:
The number 681 fits into 2410 3 times, leaving a remainder of 367.
Use 3 as the next digit of our solution. 
Result so far: 57859.3
Deduct 2043 from 2410 and we're left with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Advancing to step 10:
681 can be fit into 3670 5 times, resulting in a remainder of 265.
Write down 5 as next digit of the result. 
Result so far: 57859.35
The remainder is 265 after subtracting 3405 from 3670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 11:
The number 681 fits into 2650 3 times, leaving a remainder of 607.
Write down 3 as next digit of the result. 
Result so far: 57859.353
Deduct 2043 from 2650 and we're left with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Step 12:
681 goes into 6070 8 times with a remainder of 622.
The number 8 becomes the next digit in our result. 
Result so far: 57859.3538
If we take 5448 away from 6070, we end up with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Advancing to step 13:
When dividing 6220 by 681, we get 9 with a remainder of 91.
The number 9 becomes the next digit in our result. 
Result so far: 57859.35389
Subtract 6129 from 6220 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 14:
If we divide 910 by 681, we get 1 and a remainder of 229.
Put 1 as the next digit of the answer. 
Result so far: 57859.353891
If we take 681 away from 910, we end up with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Let's proceed to step 15:
When dividing 2290 by 681, we get 3 with a remainder of 247.
The number 3 becomes the next digit in our result. 
Result so far: 57859.3538913
Subtract 2043 from 2290 to get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Going ahead to step 16:
681 can be fit into 2470 3 times, resulting in a remainder of 427.
Use 3 as the next digit of our solution. 
Result so far: 57859.35389133
Subtract 2043 from 2470 to get 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

The final result is 57859.35389133 with a remainder of 4.27e-07.
