We're dividing 77592586 by 786 
The aim is to understand the frequency of 786 in 77592586.

Going ahead to step 1:
When dividing 7 by 786, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 786

Let's proceed to step 2:
When dividing 77 by 786, we get 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 786

Advancing to step 3:
786 can be fit into 775 0 times, resulting in a remainder of 775.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 775, we get 775.
Append the next digit (9) from the dividend to 775 and continue with: 7759 / 786

Going ahead to step 4:
The number 786 fits into 7759 9 times, leaving a remainder of 685.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7074 from 7759, we get 685.
Append the next digit (2) from the dividend to 685 and continue with: 6852 / 786

Advancing to step 5:
The number 786 fits into 6852 8 times, leaving a remainder of 564.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Deduct 6288 from 6852 and we're left with 564.
Bring next digit (5) of the dividend behind the 564 and repeat the process: 5645 / 786

Step 6:
The number 786 fits into 5645 7 times, leaving a remainder of 143.
Put 7 as the next digit of the answer. 
Result so far: 987.0
If we take 5502 away from 5645, we end up with 143.
Bring next digit (8) of the dividend behind the 143 and repeat the process: 1438 / 786

On to step 7:
If we divide 1438 by 786, we get 1 and a remainder of 652.
The next digit of our result is 1. 
Result so far: 9871.0
The remainder is 652 after subtracting 786 from 1438.
Include the next digit (6) from the dividend after 652, then repeat: 6526 / 786

Going ahead to step 8:
The number 786 fits into 6526 8 times, leaving a remainder of 238.
The number 8 becomes the next digit in our result. 
Result so far: 98718.0
If we subtract 6288 from 6526, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 9:
When dividing 2380 by 786, we get 3 with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 98718.3
The remainder is 22 after subtracting 2358 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
If we divide 220 by 786, we get 0 and a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 98718.3
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 11:
786 goes into 2200 2 times with a remainder of 628.
Record the quotient 2 as the next digit in the result. 
Result so far: 98718.302
Subtract 1572 from 2200 to get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Step 12:
When dividing 6280 by 786, we get 7 with a remainder of 778.
The next digit of our result is 7. 
Result so far: 98718.3027
The remainder is 778 after subtracting 5502 from 6280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Advancing to step 13:
When dividing 7780 by 786, we get 9 with a remainder of 706.
Use 9 as the next digit of our solution. 
Result so far: 98718.30279
If we take 7074 away from 7780, we end up with 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Going ahead to step 14:
786 can be fit into 7060 8 times, resulting in a remainder of 772.
The next digit of our result is 8. 
Result so far: 98718.302798
Subtract 6288 from 7060 to get 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

On to step 15:
7720 divided by 786 is 9 with a remainder of 646.
Record the quotient 9 as the next digit in the result. 
Result so far: 98718.3027989
Subtract 7074 from 7720 to get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

On to step 16:
The number 786 fits into 6460 8 times, leaving a remainder of 172.
The next digit of our result is 8. 
Result so far: 98718.30279898
Subtracting 6288 from 6460 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Our division results in 98718.30279898 with a remaining 1.72e-07.
