We divide 639936 by 67
We want to divide 639936 by 67.

Let's proceed to step 1:
When dividing 6 by 67, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 67

Going ahead to step 2:
When dividing 63 by 67, we get 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 67

Advancing to step 3:
If we divide 639 by 67, we get 9 and a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 603 away from 639, we end up with 36.
Grab the next digit (9) from the dividend, add it to 36, then carry on: 369 / 67

Moving on to step 4:
The number 67 fits into 369 5 times, leaving a remainder of 34.
The next digit of our result is 5. 
Result so far: 95.0
Deduct 335 from 369 and we're left with 34.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 67

Going ahead to step 5:
67 goes into 343 5 times with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 955.0
Subtracting 335 from 343 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 67

On to step 6:
The number 67 fits into 86 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 9551.0
Subtract 67 from 86 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
67 goes into 190 2 times with a remainder of 56.
The next digit of our result is 2. 
Result so far: 9551.2
Deduct 134 from 190 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.

Advancing to step 8:
67 goes into 560 8 times with a remainder of 24.
The next digit of our result is 8. 
Result so far: 9551.28
The remainder is 24 after subtracting 536 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
The number 67 fits into 240 3 times, leaving a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 9551.283
Subtract 201 from 240 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 10:
If we divide 390 by 67, we get 5 and a remainder of 55.
The next digit of our result is 5. 
Result so far: 9551.2835
The remainder is 55 after subtracting 335 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 11:
If we divide 550 by 67, we get 8 and a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 9551.28358
The remainder is 14 after subtracting 536 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
140 divided by 67 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 9551.283582
Deduct 134 from 140 and we're left 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.

Going ahead to step 13:
If we divide 60 by 67, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 9551.283582
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.

Let's proceed to step 14:
67 goes into 600 8 times with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 9551.28358208
Subtract 536 from 600 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.

Our division results in 9551.28358208 with a remaining 6.4e-08.
