We look at the division of 639470 by 76 
We want to figure out the number of times 639470 can be divided by 76.

Let's proceed to step 1:
If we divide 6 by 76, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 76

Step 2:
The number 76 fits into 63 0 times, leaving a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 76

Going ahead to step 3:
If we divide 639 by 76, we get 8 and a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 608 from 639 and we're left with 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 76

Moving on to step 4:
314 divided by 76 is 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 84.0
If we subtract 304 from 314, we get 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 76

Step 5:
The number 76 fits into 107 1 times, leaving a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 841.0
If we subtract 76 from 107, we get 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 76

Step 6:
76 goes into 310 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 8414.0
Subtracting 304 from 310 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
60 divided by 76 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 8414.0
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
600 divided by 76 is 7 with a remainder of 68.
The next digit of our result is 7. 
Result so far: 8414.07
Subtracting 532 from 600 leaves us 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.

Advancing to step 9:
76 can be fit into 680 8 times, resulting in a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 8414.078
If we take 608 away from 680, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
720 divided by 76 is 9 with a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 8414.0789
Subtracting 684 from 720 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
The number 76 fits into 360 4 times, leaving a remainder of 56.
The next digit of our result is 4. 
Result so far: 8414.07894
Deduct 304 from 360 and we're left 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.

Step 12:
560 divided by 76 is 7 with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 8414.078947
Subtract 532 from 560 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
If we divide 280 by 76, we get 3 and a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 8414.0789473
The remainder is 52 after subtracting 228 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 14:
76 goes into 520 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 8414.07894736
Subtract 456 from 520 to 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.

After the division, we end up with 8414.07894736 and a remainder of 6.4e-08.
