We're dividing 948388 by 78 
The aim is to understand the frequency of 78 in 948388.

Moving on to step 1:
9 divided by 78 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 78

Moving on to step 2:
78 goes into 94 1 times with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 78 away from 94, we end up with 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 78

Step 3:
168 divided by 78 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 12 after subtracting 156 from 168.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 78

Let's proceed to step 4:
The number 78 fits into 123 1 times, leaving a remainder of 45.
The next digit of our result is 1. 
Result so far: 121.0
Deduct 78 from 123 and we're left with 45.
Bring next digit (8) of the dividend behind the 45 and repeat the process: 458 / 78

On to step 5:
458 divided by 78 is 5 with a remainder of 68.
The next digit of our result is 5. 
Result so far: 1215.0
If we subtract 390 from 458, we get 68.
Fetch the next digit (8) from the dividend, attach it to 68 and continue: 688 / 78

On to step 6:
688 divided by 78 is 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 12158.0
Deduct 624 from 688 and we're left with 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 7:
78 goes into 640 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 12158.8
If we take 624 away from 640, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
160 divided by 78 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 12158.82
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
78 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 12158.82
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
78 goes into 400 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 12158.8205
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.

Advancing to step 11:
78 can be fit into 100 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 12158.82051
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.

Moving on to step 12:
78 goes into 220 2 times with a remainder of 64.
The next digit of our result is 2. 
Result so far: 12158.820512
If we take 156 away from 220, we end up with 64.
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 13:
When dividing 640 by 78, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 12158.8205128
Deduct 624 from 640 and we're left with 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 14:
If we divide 160 by 78, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 12158.82051282
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 12158.82051282, with a leftover of 4e-09.
