61910 ÷ 78 
The aim is to understand the frequency of 78 in 61910.

Going ahead to step 1:
78 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 78

Going ahead to step 2:
When dividing 61 by 78, we get 0 with a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Take the next digit (9) from the dividend and append it to 61, then repeat: 619 / 78

On to step 3:
If we divide 619 by 78, we get 7 and a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 546 from 619 to get 73.
Take the next digit (1) from the dividend and append it to 73, then repeat: 731 / 78

Moving on to step 4:
When dividing 731 by 78, we get 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
The remainder is 29 after subtracting 702 from 731.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 78

On to step 5:
When dividing 290 by 78, we get 3 with a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 793.0
Subtracting 234 from 290 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.

Moving on to step 6:
78 goes into 560 7 times with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 793.7
Deduct 546 from 560 and we're left 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.

Advancing to step 7:
If we divide 140 by 78, we get 1 and a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 793.71
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.

On to step 8:
The number 78 fits into 620 7 times, leaving a remainder of 74.
The next digit of our result is 7. 
Result so far: 793.717
Subtracting 546 from 620 leaves us 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.

Going ahead to step 9:
When dividing 740 by 78, we get 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 793.7179
If we subtract 702 from 740, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
78 goes into 380 4 times with a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 793.71794
The remainder is 68 after subtracting 312 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 11:
78 can be fit into 680 8 times, resulting in a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 793.717948
If we subtract 624 from 680, we get 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 12:
560 divided by 78 is 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 793.7179487
Deduct 546 from 560 and we're left 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.

On to step 13:
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: 793.71794871
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 793.71794871 and a remainder of 6.2e-08.
