We look at the division of 848212 by 78 
The aim is to understand the frequency of 78 in 848212.

Moving on to step 1:
If we divide 8 by 78, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 78

Let's proceed to step 2:
The number 78 fits into 84 1 times, leaving a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 78 from 84 leaves us with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 78

Advancing to step 3:
78 goes into 68 0 times with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 68, we get 68.
Bring next digit (2) of the dividend behind the 68 and repeat the process: 682 / 78

Advancing to step 4:
682 divided by 78 is 8 with a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 108.0
The remainder is 58 after subtracting 624 from 682.
Bring next digit (1) of the dividend behind the 58 and repeat the process: 581 / 78

Going ahead to step 5:
The number 78 fits into 581 7 times, leaving a remainder of 35.
The next digit of our result is 7. 
Result so far: 1087.0
The remainder is 35 after subtracting 546 from 581.
Append the next digit (2) from the dividend to 35 and continue with: 352 / 78

On to step 6:
If we divide 352 by 78, we get 4 and a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 10874.0
Deduct 312 from 352 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
When dividing 400 by 78, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 10874.5
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 78, we get 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 10874.51
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
The number 78 fits into 220 2 times, leaving a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 10874.512
If we subtract 156 from 220, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
640 divided by 78 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 10874.5128
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
160 divided by 78 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 10874.51282
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
78 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10874.51282
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
78 goes into 400 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 10874.5128205
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
If we divide 100 by 78, we get 1 and a remainder of 22.
The next digit of our result is 1. 
Result so far: 10874.51282051
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 10874.51282051 with a remaining 2.2e-08.
