We're dividing 97810012 by 39 
The aim is to understand the frequency of 39 in 97810012.

Advancing to step 1:
The number 39 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 39

Advancing to step 2:
If we divide 97 by 39, we get 2 and a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 78 away from 97, we end up with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 39

Let's proceed to step 3:
When dividing 198 by 39, we get 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 195 away from 198, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 39

On to step 4:
31 divided by 39 is 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 250.0
If we take 0 away from 31, we end up with 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 39

Let's proceed to step 5:
When dividing 310 by 39, we get 7 with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 2507.0
Deduct 273 from 310 and we're left with 37.
Grab the next digit (0) from the dividend, add it to 37, then carry on: 370 / 39

Going ahead to step 6:
370 divided by 39 is 9 with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 25079.0
Deduct 351 from 370 and we're left with 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 39

Moving on to step 7:
39 goes into 191 4 times with a remainder of 35.
Write down 4 as next digit of the result. 
Result so far: 250794.0
Subtracting 156 from 191 leaves us with 35.
Fetch the next digit (2) from the dividend, attach it to 35 and continue: 352 / 39

Going ahead to step 8:
39 goes into 352 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 2507949.0
Subtract 351 from 352 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
39 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 2507949.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
39 can be fit into 100 2 times, resulting in a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 2507949.02
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
39 goes into 220 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 2507949.025
The remainder is 25 after subtracting 195 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 12:
39 goes into 250 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 2507949.0256
If we subtract 234 from 250, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
The number 39 fits into 160 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 2507949.02564
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
If we divide 40 by 39, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 2507949.025641
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 15:
The number 39 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 2507949.025641
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 16:
When dividing 100 by 39, we get 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 2507949.02564102
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 2507949.02564102 with a remaining 2.2e-08.
