69795251 ÷ 786 
The aim is to understand the frequency of 786 in 69795251.

Let's proceed to step 1:
When dividing 6 by 786, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 786

Advancing to step 2:
786 goes into 69 0 times with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Bring next digit (7) of the dividend behind the 69 and repeat the process: 697 / 786

Let's proceed to step 3:
When dividing 697 by 786, we get 0 with a remainder of 697.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 697, we end up with 697.
Include the next digit (9) from the dividend after 697, then repeat: 6979 / 786

Going ahead to step 4:
The number 786 fits into 6979 8 times, leaving a remainder of 691.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 6288 from 6979, we get 691.
Grab the next digit (5) from the dividend, add it to 691, then carry on: 6915 / 786

Step 5:
When dividing 6915 by 786, we get 8 with a remainder of 627.
Write down 8 as next digit of the result. 
Result so far: 88.0
The remainder is 627 after subtracting 6288 from 6915.
Grab the next digit (2) from the dividend, add it to 627, then carry on: 6272 / 786

Advancing to step 6:
6272 divided by 786 is 7 with a remainder of 770.
The number 7 becomes the next digit in our result. 
Result so far: 887.0
Subtract 5502 from 6272 to get 770.
Grab the next digit (5) from the dividend, add it to 770, then carry on: 7705 / 786

Advancing to step 7:
If we divide 7705 by 786, we get 9 and a remainder of 631.
Use 9 as the next digit of our solution. 
Result so far: 8879.0
Subtract 7074 from 7705 to get 631.
Include the next digit (1) from the dividend after 631, then repeat: 6311 / 786

On to step 8:
786 can be fit into 6311 8 times, resulting in a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 88798.0
If we take 6288 away from 6311, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
786 can be fit into 230 0 times, resulting in a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 88798.0
The remainder is 230 after subtracting 0 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 10:
If we divide 2300 by 786, we get 2 and a remainder of 728.
The number 2 becomes the next digit in our result. 
Result so far: 88798.02
Deduct 1572 from 2300 and we're left with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Let's proceed to step 11:
786 goes into 7280 9 times with a remainder of 206.
The next digit of our result is 9. 
Result so far: 88798.029
Subtract 7074 from 7280 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 12:
786 can be fit into 2060 2 times, resulting in a remainder of 488.
Put 2 as the next digit of the answer. 
Result so far: 88798.0292
Subtract 1572 from 2060 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Advancing to step 13:
786 goes into 4880 6 times with a remainder of 164.
Put 6 as the next digit of the answer. 
Result so far: 88798.02926
The remainder is 164 after subtracting 4716 from 4880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 14:
The number 786 fits into 1640 2 times, leaving a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 88798.029262
If we subtract 1572 from 1640, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 15:
The number 786 fits into 680 0 times, leaving a remainder of 680.
Use 0 as the next digit of our solution. 
Result so far: 88798.029262
Deduct 0 from 680 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Moving on to step 16:
786 goes into 6800 8 times with a remainder of 512.
The next digit of our result is 8. 
Result so far: 88798.02926208
Subtracting 6288 from 6800 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

After the division, we end up with 88798.02926208 and a remainder of 5.12e-07.
