Let's divide 616217 by 78
The aim is to understand the frequency of 78 in 616217.

Advancing to step 1:
If we divide 6 by 78, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 78

On to step 2:
78 can be fit into 61 0 times, resulting in a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Grab the next digit (6) from the dividend, add it to 61, then carry on: 616 / 78

Let's proceed to step 3:
If we divide 616 by 78, we get 7 and a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 546 from 616 to get 70.
Grab the next digit (2) from the dividend, add it to 70, then carry on: 702 / 78

Going ahead to step 4:
702 divided by 78 is 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 79.0
The remainder is 0 after subtracting 702 from 702.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 78

Step 5:
78 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 790.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 78

Let's proceed to step 6:
78 can be fit into 17 0 times, resulting in a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 7900.0
The remainder is 17 after subtracting 0 from 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
If we divide 170 by 78, we get 2 and a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 7900.2
The remainder is 14 after subtracting 156 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
If we divide 140 by 78, we get 1 and a remainder of 62.
The next digit of our result is 1. 
Result so far: 7900.21
The remainder is 62 after subtracting 78 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
620 divided by 78 is 7 with a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 7900.217
Deduct 546 from 620 and we're left 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.

Step 10:
The number 78 fits into 740 9 times, leaving a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 7900.2179
Deduct 702 from 740 and we're left 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.

Let's proceed to step 11:
78 can be fit into 380 4 times, resulting in a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 7900.21794
Subtracting 312 from 380 leaves us with 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 12:
78 goes into 680 8 times with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 7900.217948
Subtracting 624 from 680 leaves us 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.

On to step 13:
560 divided by 78 is 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 7900.2179487
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.

Let's proceed to step 14:
78 can be fit into 140 1 times, resulting in a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 7900.21794871
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.

After the division, we end up with 7900.21794871 and a remainder of 6.2e-08.
