We're dividing 886198 by 78 
The aim is to understand the frequency of 78 in 886198.

On to step 1:
When dividing 8 by 78, we get 0 with 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.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 78

Advancing to step 2:
78 can be fit into 88 1 times, resulting in a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 78 from 88 to get 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 78

Moving on to step 3:
78 can be fit into 106 1 times, resulting in a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 78 from 106 and we're left with 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 78

Let's proceed to step 4:
The number 78 fits into 281 3 times, leaving a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
If we subtract 234 from 281, we get 47.
Fetch the next digit (9) from the dividend, attach it to 47 and continue: 479 / 78

Moving on to step 5:
78 can be fit into 479 6 times, resulting in a remainder of 11.
The next digit of our result is 6. 
Result so far: 1136.0
The remainder is 11 after subtracting 468 from 479.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 78

Step 6:
The number 78 fits into 118 1 times, leaving a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 11361.0
If we take 78 away from 118, 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 7:
If we divide 400 by 78, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 11361.5
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
78 can be fit into 100 1 times, resulting in a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 11361.51
If we subtract 78 from 100, we 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.

Moving on to step 9:
When dividing 220 by 78, we get 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 11361.512
The remainder is 64 after subtracting 156 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
640 divided by 78 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 11361.5128
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
160 divided by 78 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 11361.51282
Deduct 156 from 160 and we're left 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.

Moving on to step 12:
40 divided by 78 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 11361.51282
Subtracting 0 from 40 leaves us 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:
If we divide 400 by 78, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 11361.5128205
Deduct 390 from 400 and we're left 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.

Going ahead to step 14:
78 goes into 100 1 times with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 11361.51282051
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.

The final result is 11361.51282051 with a remainder of 2.2e-08.
