We divide 363903 by 39
The aim is to understand the frequency of 39 in 363903.

Going ahead to step 1:
39 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 39

Let's proceed to step 2:
39 can be fit into 36 0 times, resulting in a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 39

Let's proceed to step 3:
If we divide 363 by 39, we get 9 and a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 351 from 363 to get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 39

Going ahead to step 4:
39 can be fit into 129 3 times, resulting in a remainder of 12.
The next digit of our result is 3. 
Result so far: 93.0
Subtracting 117 from 129 leaves us with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 39

Moving on to step 5:
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: 933.0
Subtract 117 from 120 to get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 39

Going ahead to step 6:
When dividing 33 by 39, we get 0 with a remainder of 33.
The next digit of our result is 0. 
Result so far: 9330.0
The remainder is 33 after subtracting 0 from 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
When dividing 330 by 39, we get 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 9330.8
If we take 312 away from 330, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
39 goes into 180 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 9330.84
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
The number 39 fits into 240 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 9330.846
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
When dividing 60 by 39, we get 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 9330.8461
If we take 39 away from 60, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 11:
When dividing 210 by 39, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 9330.84615
Subtract 195 from 210 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
150 divided by 39 is 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 9330.846153
The remainder is 33 after subtracting 117 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 13:
330 divided by 39 is 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 9330.8461538
The remainder is 18 after subtracting 312 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
When dividing 180 by 39, we get 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 9330.84615384
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 9330.84615384 with a remaining 2.4e-08.
