We're dividing 39088949 by 786 
The aim is to understand the frequency of 786 in 39088949.

Going ahead to step 1:
If we divide 3 by 786, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 786

Moving on to step 2:
39 divided by 786 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 786

Advancing to step 3:
The number 786 fits into 390 0 times, leaving a remainder of 390.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 390 leaves us with 390.
Append the next digit (8) from the dividend to 390 and continue with: 3908 / 786

Moving on to step 4:
786 can be fit into 3908 4 times, resulting in a remainder of 764.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 3144 from 3908, we get 764.
Include the next digit (8) from the dividend after 764, then repeat: 7648 / 786

Advancing to step 5:
When dividing 7648 by 786, we get 9 with a remainder of 574.
The next digit of our result is 9. 
Result so far: 49.0
If we subtract 7074 from 7648, we get 574.
Bring next digit (9) of the dividend behind the 574 and repeat the process: 5749 / 786

Advancing to step 6:
786 can be fit into 5749 7 times, resulting in a remainder of 247.
Use 7 as the next digit of our solution. 
Result so far: 497.0
The remainder is 247 after subtracting 5502 from 5749.
Take the next digit (4) from the dividend and append it to 247, then repeat: 2474 / 786

On to step 7:
2474 divided by 786 is 3 with a remainder of 116.
The number 3 becomes the next digit in our result. 
Result so far: 4973.0
The remainder is 116 after subtracting 2358 from 2474.
Take the next digit (9) from the dividend and append it to 116, then repeat: 1169 / 786

On to step 8:
When dividing 1169 by 786, we get 1 with a remainder of 383.
Write down 1 as next digit of the result. 
Result so far: 49731.0
Subtracting 786 from 1169 leaves us with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Going ahead to step 9:
When dividing 3830 by 786, we get 4 with a remainder of 686.
Put 4 as the next digit of the answer. 
Result so far: 49731.4
Deduct 3144 from 3830 and we're left with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Step 10:
6860 divided by 786 is 8 with a remainder of 572.
The next digit of our result is 8. 
Result so far: 49731.48
If we take 6288 away from 6860, we end up with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Advancing to step 11:
When dividing 5720 by 786, we get 7 with a remainder of 218.
Record the quotient 7 as the next digit in the result. 
Result so far: 49731.487
The remainder is 218 after subtracting 5502 from 5720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 12:
786 goes into 2180 2 times with a remainder of 608.
Record the quotient 2 as the next digit in the result. 
Result so far: 49731.4872
Deduct 1572 from 2180 and we're left with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

On to step 13:
If we divide 6080 by 786, we get 7 and a remainder of 578.
The next digit of our result is 7. 
Result so far: 49731.48727
Subtract 5502 from 6080 to get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Step 14:
786 can be fit into 5780 7 times, resulting in a remainder of 278.
The number 7 becomes the next digit in our result. 
Result so far: 49731.487277
If we subtract 5502 from 5780, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

The final outcome is 49731.487277, with a leftover of 2.78e-05.
