We look at the division of 39989730 by 679 
The aim is to understand the frequency of 679 in 39989730.

Step 1:
679 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 679

On to step 2:
When dividing 39 by 679, we get 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 679

Let's proceed to step 3:
679 can be fit into 399 0 times, resulting in a remainder of 399.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 399 leaves us with 399.
Include the next digit (8) from the dividend after 399, then repeat: 3998 / 679

Advancing to step 4:
If we divide 3998 by 679, we get 5 and a remainder of 603.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 3395 from 3998 leaves us with 603.
Fetch the next digit (9) from the dividend, attach it to 603 and continue: 6039 / 679

Step 5:
When dividing 6039 by 679, we get 8 with a remainder of 607.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Subtracting 5432 from 6039 leaves us with 607.
Fetch the next digit (7) from the dividend, attach it to 607 and continue: 6077 / 679

Moving on to step 6:
When dividing 6077 by 679, we get 8 with a remainder of 645.
Record the quotient 8 as the next digit in the result. 
Result so far: 588.0
Subtract 5432 from 6077 to get 645.
Take the next digit (3) from the dividend and append it to 645, then repeat: 6453 / 679

Advancing to step 7:
When dividing 6453 by 679, we get 9 with a remainder of 342.
Use 9 as the next digit of our solution. 
Result so far: 5889.0
If we subtract 6111 from 6453, we get 342.
Fetch the next digit (0) from the dividend, attach it to 342 and continue: 3420 / 679

Moving on to step 8:
3420 divided by 679 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 58895.0
Deduct 3395 from 3420 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
679 can be fit into 250 0 times, resulting in a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 58895.0
If we take 0 away from 250, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 10:
The number 679 fits into 2500 3 times, leaving a remainder of 463.
The next digit of our result is 3. 
Result so far: 58895.03
Subtract 2037 from 2500 to get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

On to step 11:
If we divide 4630 by 679, we get 6 and a remainder of 556.
The number 6 becomes the next digit in our result. 
Result so far: 58895.036
Subtract 4074 from 4630 to get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Advancing to step 12:
679 goes into 5560 8 times with a remainder of 128.
Put 8 as the next digit of the answer. 
Result so far: 58895.0368
If we subtract 5432 from 5560, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 13:
679 can be fit into 1280 1 times, resulting in a remainder of 601.
Write down 1 as next digit of the result. 
Result so far: 58895.03681
If we take 679 away from 1280, we end up with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Step 14:
679 goes into 6010 8 times with a remainder of 578.
The number 8 becomes the next digit in our result. 
Result so far: 58895.036818
Subtracting 5432 from 6010 leaves us with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Moving on to step 15:
The number 679 fits into 5780 8 times, leaving a remainder of 348.
Record the quotient 8 as the next digit in the result. 
Result so far: 58895.0368188
If we take 5432 away from 5780, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

The final result is 58895.0368188 with a remainder of 3.48e-06.
