864293 ÷ 78 
The aim is to understand the frequency of 78 in 864293.

On to step 1:
78 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 78

Going ahead to step 2:
86 divided by 78 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 78 from 86, we get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 78

Going ahead to step 3:
78 goes into 84 1 times with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 78 away from 84, we end up with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 78

On to step 4:
78 can be fit into 62 0 times, resulting in a remainder of 62.
The next digit of our result is 0. 
Result so far: 110.0
Subtracting 0 from 62 leaves us with 62.
Fetch the next digit (9) from the dividend, attach it to 62 and continue: 629 / 78

Step 5:
The number 78 fits into 629 8 times, leaving a remainder of 5.
The next digit of our result is 8. 
Result so far: 1108.0
Deduct 624 from 629 and we're left with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 78

Step 6:
53 divided by 78 is 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 11080.0
The remainder is 53 after subtracting 0 from 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 7:
78 goes into 530 6 times with a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 11080.6
If we take 468 away from 530, 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.

Advancing to step 8:
When dividing 620 by 78, we get 7 with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 11080.67
Deduct 546 from 620 and we're left with 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 9:
78 goes into 740 9 times with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 11080.679
If we subtract 702 from 740, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 10:
When dividing 380 by 78, we get 4 with a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 11080.6794
Subtracting 312 from 380 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 11:
78 goes into 680 8 times with a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 11080.67948
If we take 624 away from 680, we end up 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.

Moving on to step 12:
560 divided by 78 is 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 11080.679487
Deduct 546 from 560 and we're left with 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 13:
If we divide 140 by 78, we get 1 and a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 11080.6794871
Subtract 78 from 140 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 14:
78 goes into 620 7 times with a remainder of 74.
The next digit of our result is 7. 
Result so far: 11080.67948717
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.

The quotient of the division is 11080.67948717, and the remainder is 7.4e-08.
