258617 divided by 39 
The aim is to understand the frequency of 39 in 258617.

Going ahead to step 1:
When dividing 2 by 39, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 39

Advancing to step 2:
25 divided by 39 is 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 39

Advancing to step 3:
The number 39 fits into 258 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 234 away from 258, we end up with 24.
Fetch the next digit (6) from the dividend, attach it to 24 and continue: 246 / 39

Moving on to step 4:
The number 39 fits into 246 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 66.0
Deduct 234 from 246 and we're left with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 39

On to step 5:
When dividing 121 by 39, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 663.0
Subtracting 117 from 121 leaves us with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 39

Going ahead to step 6:
47 divided by 39 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 6631.0
Deduct 39 from 47 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
If we divide 80 by 39, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 6631.2
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
If we divide 20 by 39, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 6631.2
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
When dividing 200 by 39, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 6631.205
The remainder is 5 after subtracting 195 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
50 divided by 39 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 6631.2051
Deduct 39 from 50 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 11:
If we divide 110 by 39, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 6631.20512
If we subtract 78 from 110, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
39 goes into 320 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 6631.205128
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
When dividing 80 by 39, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 6631.2051282
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
When dividing 20 by 39, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 6631.2051282
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 6631.2051282, and the remainder is 2e-08.
