70216124 ÷ 786 
The aim is to understand the frequency of 786 in 70216124.

Moving on to step 1:
When dividing 7 by 786, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 786

Moving on to step 2:
70 divided by 786 is 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Include the next digit (2) from the dividend after 70, then repeat: 702 / 786

Moving on to step 3:
702 divided by 786 is 0 with a remainder of 702.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 702, we get 702.
Bring next digit (1) of the dividend behind the 702 and repeat the process: 7021 / 786

Going ahead to step 4:
If we divide 7021 by 786, we get 8 and a remainder of 733.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 733 after subtracting 6288 from 7021.
Fetch the next digit (6) from the dividend, attach it to 733 and continue: 7336 / 786

On to step 5:
786 goes into 7336 9 times with a remainder of 262.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
The remainder is 262 after subtracting 7074 from 7336.
Fetch the next digit (1) from the dividend, attach it to 262 and continue: 2621 / 786

Step 6:
If we divide 2621 by 786, we get 3 and a remainder of 263.
The next digit of our result is 3. 
Result so far: 893.0
If we subtract 2358 from 2621, we get 263.
Take the next digit (2) from the dividend and append it to 263, then repeat: 2632 / 786

Step 7:
2632 divided by 786 is 3 with a remainder of 274.
Record the quotient 3 as the next digit in the result. 
Result so far: 8933.0
Subtracting 2358 from 2632 leaves us with 274.
Take the next digit (4) from the dividend and append it to 274, then repeat: 2744 / 786

Moving on to step 8:
786 goes into 2744 3 times with a remainder of 386.
Put 3 as the next digit of the answer. 
Result so far: 89333.0
If we subtract 2358 from 2744, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Moving on to step 9:
3860 divided by 786 is 4 with a remainder of 716.
Use 4 as the next digit of our solution. 
Result so far: 89333.4
The remainder is 716 after subtracting 3144 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Step 10:
When dividing 7160 by 786, we get 9 with a remainder of 86.
The next digit of our result is 9. 
Result so far: 89333.49
The remainder is 86 after subtracting 7074 from 7160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 11:
786 goes into 860 1 times with a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 89333.491
The remainder is 74 after subtracting 786 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 12:
786 goes into 740 0 times with a remainder of 740.
The next digit of our result is 0. 
Result so far: 89333.491
Deduct 0 from 740 and we're left with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Going ahead to step 13:
7400 divided by 786 is 9 with a remainder of 326.
The number 9 becomes the next digit in our result. 
Result so far: 89333.49109
The remainder is 326 after subtracting 7074 from 7400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 14:
When dividing 3260 by 786, we get 4 with a remainder of 116.
The number 4 becomes the next digit in our result. 
Result so far: 89333.491094
If we subtract 3144 from 3260, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 15:
1160 divided by 786 is 1 with a remainder of 374.
The next digit of our result is 1. 
Result so far: 89333.4910941
If we subtract 786 from 1160, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Going ahead to step 16:
The number 786 fits into 3740 4 times, leaving a remainder of 596.
The next digit of our result is 4. 
Result so far: 89333.49109414
If we take 3144 away from 3740, we end up with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

The quotient of the division is 89333.49109414, and the remainder is 5.96e-07.
