We divide 121707 by 39
The aim is to understand the frequency of 39 in 121707.

Going ahead to step 1:
1 divided by 39 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 39

Advancing to step 2:
The number 39 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 39

Going ahead to step 3:
39 can be fit into 121 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 117 from 121 and we're left with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 39

Step 4:
47 divided by 39 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we subtract 39 from 47, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 39

Going ahead to step 5:
The number 39 fits into 80 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 312.0
Deduct 78 from 80 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 39

Advancing to step 6:
The number 39 fits into 27 0 times, leaving a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 3120.0
The remainder is 27 after subtracting 0 from 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
When dividing 270 by 39, we get 6 with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 3120.6
Subtract 234 from 270 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
39 can be fit into 360 9 times, resulting in a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 3120.69
The remainder is 9 after subtracting 351 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
90 divided by 39 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 3120.692
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
39 can be fit into 120 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3120.6923
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 11:
39 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 3120.6923
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
39 goes into 300 7 times with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 3120.692307
Deduct 273 from 300 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 13:
The number 39 fits into 270 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 3120.6923076
If we subtract 234 from 270, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
The number 39 fits into 360 9 times, leaving a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 3120.69230769
Subtract 351 from 360 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 3120.69230769, and the remainder is 9e-09.
