Let's divide 640119 by 78
We want to figure out the number of times 640119 can be divided by 78.

Advancing to step 1:
The number 78 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 78

Step 2:
78 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Grab the next digit (0) from the dividend, add it to 64, then carry on: 640 / 78

On to step 3:
78 can be fit into 640 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 624 from 640, we get 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 78

Let's proceed to step 4:
78 can be fit into 161 2 times, resulting in a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 82.0
Subtract 156 from 161 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 78

On to step 5:
If we divide 51 by 78, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 820.0
Deduct 0 from 51 and we're left with 51.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 78

Step 6:
519 divided by 78 is 6 with a remainder of 51.
Write down 6 as next digit of the result. 
Result so far: 8206.0
If we subtract 468 from 519, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
When dividing 510 by 78, we get 6 with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 8206.6
Deduct 468 from 510 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
When dividing 420 by 78, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 8206.65
Subtract 390 from 420 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
The number 78 fits into 300 3 times, leaving a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 8206.653
If we take 234 away from 300, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 10:
The number 78 fits into 660 8 times, leaving a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 8206.6538
Subtract 624 from 660 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
If we divide 360 by 78, we get 4 and a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 8206.65384
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
78 goes into 480 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 8206.653846
The remainder is 12 after subtracting 468 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
120 divided by 78 is 1 with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 8206.6538461
Deduct 78 from 120 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 14:
78 can be fit into 420 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 8206.65384615
If we take 390 away from 420, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 8206.65384615 with a balance of 3e-08.
