We look at the division of 648194 by 78 
We want to figure out the number of times 648194 can be divided by 78.

Advancing to step 1:
If we divide 6 by 78, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 78

On to step 2:
78 goes into 64 0 times with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Append the next digit (8) from the dividend to 64 and continue with: 648 / 78

On to step 3:
78 goes into 648 8 times with a remainder of 24.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 624 from 648 and we're left with 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 78

Going ahead to step 4:
If we divide 241 by 78, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
The remainder is 7 after subtracting 234 from 241.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 78

Moving on to step 5:
The number 78 fits into 79 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 831.0
Subtract 78 from 79 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 78

On to step 6:
78 can be fit into 14 0 times, resulting in a remainder of 14.
The next digit of our result is 0. 
Result so far: 8310.0
If we subtract 0 from 14, we get 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 7:
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: 8310.1
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.

Advancing to step 8:
When dividing 620 by 78, we get 7 with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 8310.17
If we subtract 546 from 620, we get 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:
The number 78 fits into 740 9 times, leaving a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 8310.179
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.

Step 10:
When dividing 380 by 78, we get 4 with a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 8310.1794
Deduct 312 from 380 and we're left 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.

Step 11:
78 can be fit into 680 8 times, resulting in a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 8310.17948
The remainder is 56 after subtracting 624 from 680.
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:
78 goes into 560 7 times with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 8310.179487
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 13:
140 divided by 78 is 1 with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 8310.1794871
Subtracting 78 from 140 leaves us 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.

Advancing to step 14:
When dividing 620 by 78, we get 7 with a remainder of 74.
The next digit of our result is 7. 
Result so far: 8310.17948717
If we take 546 away from 620, we end up 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.

Our division results in 8310.17948717 with a remaining 7.4e-08.
