681703 divided by 78 
The aim is to understand the frequency of 78 in 681703.

On to step 1:
The number 78 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 78

Step 2:
The number 78 fits into 68 0 times, leaving a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Fetch the next digit (1) from the dividend, attach it to 68 and continue: 681 / 78

Moving on to step 3:
When dividing 681 by 78, we get 8 with a remainder of 57.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 624 from 681 and we're left with 57.
Bring next digit (7) of the dividend behind the 57 and repeat the process: 577 / 78

Let's proceed to step 4:
If we divide 577 by 78, we get 7 and a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 87.0
Subtract 546 from 577 to get 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 78

Step 5:
78 goes into 310 3 times with a remainder of 76.
The number 3 becomes the next digit in our result. 
Result so far: 873.0
Subtracting 234 from 310 leaves us with 76.
Include the next digit (3) from the dividend after 76, then repeat: 763 / 78

Step 6:
If we divide 763 by 78, we get 9 and a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 8739.0
Subtract 702 from 763 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 7:
78 can be fit into 610 7 times, resulting in a remainder of 64.
Put 7 as the next digit of the answer. 
Result so far: 8739.7
If we take 546 away from 610, 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.

Advancing to step 8:
78 can be fit into 640 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 8739.78
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
78 can be fit into 160 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 8739.782
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.

On to step 10:
40 divided by 78 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 8739.782
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.

On to step 11:
78 goes into 400 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 8739.78205
If we take 390 away from 400, we end up 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.

Step 12:
78 can be fit into 100 1 times, resulting in a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 8739.782051
The remainder is 22 after subtracting 78 from 100.
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 13:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 8739.7820512
If we subtract 156 from 220, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 14:
78 can be fit into 640 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 8739.78205128
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.

The quotient of the division is 8739.78205128, and the remainder is 1.6e-08.
