We divide 821276 by 78
The aim is to understand the frequency of 78 in 821276.

Advancing to step 1:
The number 78 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 78

Going ahead to step 2:
78 can be fit into 82 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 78 from 82 and we're left with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 78

Advancing to step 3:
When dividing 41 by 78, we get 0 with a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 41 and we're left with 41.
Append the next digit (2) from the dividend to 41 and continue with: 412 / 78

Moving on to step 4:
412 divided by 78 is 5 with a remainder of 22.
Put 5 as the next digit of the answer. 
Result so far: 105.0
Deduct 390 from 412 and we're left with 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 78

Advancing to step 5:
227 divided by 78 is 2 with a remainder of 71.
Record the quotient 2 as the next digit in the result. 
Result so far: 1052.0
Subtract 156 from 227 to get 71.
Take the next digit (6) from the dividend and append it to 71, then repeat: 716 / 78

Let's proceed to step 6:
716 divided by 78 is 9 with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 10529.0
The remainder is 14 after subtracting 702 from 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
The number 78 fits into 140 1 times, leaving a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 10529.1
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 8:
78 can be fit into 620 7 times, resulting in a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 10529.17
If we take 546 away from 620, we end up 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.

Moving on to step 9:
If we divide 740 by 78, we get 9 and a remainder of 38.
The next digit of our result is 9. 
Result so far: 10529.179
If we take 702 away from 740, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
380 divided by 78 is 4 with a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 10529.1794
If we subtract 312 from 380, 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 11:
When dividing 680 by 78, we get 8 with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 10529.17948
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.

Going ahead to step 12:
When dividing 560 by 78, we get 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 10529.179487
Subtracting 546 from 560 leaves us 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.

Moving on to step 13:
The number 78 fits into 140 1 times, leaving a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 10529.1794871
If we subtract 78 from 140, we 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.

Going ahead to step 14:
620 divided by 78 is 7 with a remainder of 74.
The next digit of our result is 7. 
Result so far: 10529.17948717
Subtract 546 from 620 to 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 final outcome is 10529.17948717, with a leftover of 7.4e-08.
