We're dividing 640788 by 76 
We want to divide 640788 by 76.

Advancing to step 1:
If we divide 6 by 76, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 76

On to step 2:
When dividing 64 by 76, we get 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 76

Step 3:
The number 76 fits into 640 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 32 after subtracting 608 from 640.
Fetch the next digit (7) from the dividend, attach it to 32 and continue: 327 / 76

Advancing to step 4:
76 can be fit into 327 4 times, resulting in a remainder of 23.
The next digit of our result is 4. 
Result so far: 84.0
Subtracting 304 from 327 leaves us with 23.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 76

Step 5:
76 can be fit into 238 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 843.0
If we subtract 228 from 238, we get 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 76

On to step 6:
108 divided by 76 is 1 with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 8431.0
If we take 76 away from 108, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
The number 76 fits into 320 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 8431.4
Deduct 304 from 320 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.

On to step 8:
The number 76 fits into 160 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 8431.42
If we take 152 away from 160, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
76 goes into 80 1 times with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 8431.421
Subtracting 76 from 80 leaves us 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.

Let's proceed to step 10:
40 divided by 76 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 8431.421
If we subtract 0 from 40, we get 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:
400 divided by 76 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 8431.42105
Deduct 380 from 400 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
When dividing 200 by 76, we get 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 8431.421052
Subtracting 152 from 200 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 13:
When dividing 480 by 76, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 8431.4210526
Subtracting 456 from 480 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
76 can be fit into 240 3 times, resulting in a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 8431.42105263
Deduct 228 from 240 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 8431.42105263, and the remainder is 1.2e-08.
