We're dividing 501205 by 78 
The aim is to understand the frequency of 78 in 501205.

Let's proceed to step 1:
78 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 78

Going ahead to step 2:
If we divide 50 by 78, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Bring next digit (1) of the dividend behind the 50 and repeat the process: 501 / 78

Step 3:
If we divide 501 by 78, we get 6 and a remainder of 33.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 468 away from 501, we end up with 33.
Grab the next digit (2) from the dividend, add it to 33, then carry on: 332 / 78

Moving on to step 4:
If we divide 332 by 78, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 64.0
Subtract 312 from 332 to get 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 78

On to step 5:
78 can be fit into 200 2 times, resulting in a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 642.0
If we take 156 away from 200, we end up with 44.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 78

On to step 6:
If we divide 445 by 78, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 6425.0
Deduct 390 from 445 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 7:
78 goes into 550 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 6425.7
If we take 546 away from 550, 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.

Let's proceed to step 8:
The number 78 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 6425.7
Deduct 0 from 40 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.

Advancing to step 9:
The number 78 fits into 400 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 6425.705
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 10:
When dividing 100 by 78, we get 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 6425.7051
If we take 78 away from 100, we end up 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.

Going ahead to step 11:
If we divide 220 by 78, we get 2 and a remainder of 64.
The next digit of our result is 2. 
Result so far: 6425.70512
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 12:
78 can be fit into 640 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 6425.705128
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.

Going ahead to step 13:
The number 78 fits into 160 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 6425.7051282
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 14:
78 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 6425.7051282
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.

The final outcome is 6425.7051282, with a leftover of 4e-08.
