We're dividing 347407 by 39 
The aim is to understand the frequency of 39 in 347407.

Step 1:
39 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 39

On to step 2:
34 divided by 39 is 0 with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Grab the next digit (7) from the dividend, add it to 34, then carry on: 347 / 39

On to step 3:
If we divide 347 by 39, we get 8 and a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 312 from 347 to get 35.
Fetch the next digit (4) from the dividend, attach it to 35 and continue: 354 / 39

Going ahead to step 4:
354 divided by 39 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 89.0
If we subtract 351 from 354, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 39

Going ahead to step 5:
30 divided by 39 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 890.0
Subtracting 0 from 30 leaves us with 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 39

Going ahead to step 6:
When dividing 307 by 39, we get 7 with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 8907.0
Subtract 273 from 307 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
The number 39 fits into 340 8 times, leaving a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 8907.8
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
The number 39 fits into 280 7 times, leaving a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 8907.87
Deduct 273 from 280 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
When dividing 70 by 39, we get 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 8907.871
If we take 39 away from 70, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 10:
If we divide 310 by 39, we get 7 and a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 8907.8717
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 11:
The number 39 fits into 370 9 times, leaving a remainder of 19.
The next digit of our result is 9. 
Result so far: 8907.87179
Subtract 351 from 370 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 12:
The number 39 fits into 190 4 times, leaving a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 8907.871794
Deduct 156 from 190 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 13:
The number 39 fits into 340 8 times, leaving a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 8907.8717948
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
39 can be fit into 280 7 times, resulting in a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 8907.87179487
Subtract 273 from 280 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 8907.87179487 with a remaining 7e-09.
