We're dividing 83026205 by 678 
The aim is to understand the frequency of 678 in 83026205.

On to step 1:
The number 678 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 678

Step 2:
678 goes into 83 0 times with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Fetch the next digit (0) from the dividend, attach it to 83 and continue: 830 / 678

Step 3:
830 divided by 678 is 1 with a remainder of 152.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 152 after subtracting 678 from 830.
Append the next digit (2) from the dividend to 152 and continue with: 1522 / 678

Step 4:
678 goes into 1522 2 times with a remainder of 166.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1356 from 1522 to get 166.
Include the next digit (6) from the dividend after 166, then repeat: 1666 / 678

Moving on to step 5:
678 goes into 1666 2 times with a remainder of 310.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
Deduct 1356 from 1666 and we're left with 310.
Fetch the next digit (2) from the dividend, attach it to 310 and continue: 3102 / 678

Going ahead to step 6:
If we divide 3102 by 678, we get 4 and a remainder of 390.
The number 4 becomes the next digit in our result. 
Result so far: 1224.0
If we subtract 2712 from 3102, we get 390.
Include the next digit (0) from the dividend after 390, then repeat: 3900 / 678

Going ahead to step 7:
3900 divided by 678 is 5 with a remainder of 510.
The next digit of our result is 5. 
Result so far: 12245.0
Deduct 3390 from 3900 and we're left with 510.
Grab the next digit (5) from the dividend, add it to 510, then carry on: 5105 / 678

Let's proceed to step 8:
5105 divided by 678 is 7 with a remainder of 359.
The next digit of our result is 7. 
Result so far: 122457.0
If we take 4746 away from 5105, we end up with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Let's proceed to step 9:
If we divide 3590 by 678, we get 5 and a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 122457.5
Subtracting 3390 from 3590 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 10:
If we divide 2000 by 678, we get 2 and a remainder of 644.
Put 2 as the next digit of the answer. 
Result so far: 122457.52
The remainder is 644 after subtracting 1356 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Going ahead to step 11:
678 goes into 6440 9 times with a remainder of 338.
Write down 9 as next digit of the result. 
Result so far: 122457.529
Subtract 6102 from 6440 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Step 12:
678 can be fit into 3380 4 times, resulting in a remainder of 668.
The number 4 becomes the next digit in our result. 
Result so far: 122457.5294
Deduct 2712 from 3380 and we're left with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Moving on to step 13:
The number 678 fits into 6680 9 times, leaving a remainder of 578.
Use 9 as the next digit of our solution. 
Result so far: 122457.52949
Subtract 6102 from 6680 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.

Advancing to step 14:
5780 divided by 678 is 8 with a remainder of 356.
Use 8 as the next digit of our solution. 
Result so far: 122457.529498
Subtracting 5424 from 5780 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 15:
678 goes into 3560 5 times with a remainder of 170.
Use 5 as the next digit of our solution. 
Result so far: 122457.5294985
If we take 3390 away from 3560, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 16:
The number 678 fits into 1700 2 times, leaving a remainder of 344.
Put 2 as the next digit of the answer. 
Result so far: 122457.52949852
Deduct 1356 from 1700 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

After the division, we end up with 122457.52949852 and a remainder of 3.44e-07.
