We're dividing 683531 by 78 
The aim is to understand the frequency of 78 in 683531.

Moving on to step 1:
The number 78 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 78

On to step 2:
78 goes into 68 0 times with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Bring next digit (3) of the dividend behind the 68 and repeat the process: 683 / 78

On to step 3:
683 divided by 78 is 8 with a remainder of 59.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 624 from 683 to get 59.
Fetch the next digit (5) from the dividend, attach it to 59 and continue: 595 / 78

Going ahead to step 4:
If we divide 595 by 78, we get 7 and a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 87.0
Subtract 546 from 595 to get 49.
Grab the next digit (3) from the dividend, add it to 49, then carry on: 493 / 78

Going ahead to step 5:
The number 78 fits into 493 6 times, leaving a remainder of 25.
Put 6 as the next digit of the answer. 
Result so far: 876.0
If we take 468 away from 493, we end up with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 78

On to step 6:
251 divided by 78 is 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 8763.0
If we subtract 234 from 251, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
If we divide 170 by 78, we get 2 and a remainder of 14.
The next digit of our result is 2. 
Result so far: 8763.2
Subtract 156 from 170 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
78 can be fit into 140 1 times, resulting in a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 8763.21
If we take 78 away from 140, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 9:
When dividing 620 by 78, we get 7 with a remainder of 74.
The next digit of our result is 7. 
Result so far: 8763.217
If we subtract 546 from 620, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 10:
78 goes into 740 9 times with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 8763.2179
The remainder is 38 after subtracting 702 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
78 goes into 380 4 times with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 8763.21794
Subtract 312 from 380 to 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.

Step 12:
The number 78 fits into 680 8 times, leaving a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 8763.217948
Subtracting 624 from 680 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 13:
If we divide 560 by 78, we get 7 and a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 8763.2179487
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 14:
78 can be fit into 140 1 times, resulting in a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 8763.21794871
Deduct 78 from 140 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Our division results in 8763.21794871 with a remaining 6.2e-08.
