We're dividing 640990 by 67 
Our goal is to divide 640990 by 67.

Advancing to step 1:
If we divide 6 by 67, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 67

Step 2:
67 goes into 64 0 times with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 67

Let's proceed to step 3:
If we divide 640 by 67, we get 9 and a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 603 from 640 and we're left with 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 67

Advancing to step 4:
379 divided by 67 is 5 with a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
Subtract 335 from 379 to get 44.
Include the next digit (9) from the dividend after 44, then repeat: 449 / 67

Moving on to step 5:
67 goes into 449 6 times with a remainder of 47.
Write down 6 as next digit of the result. 
Result so far: 956.0
Subtract 402 from 449 to get 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 67

Step 6:
When dividing 470 by 67, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 9567.0
If we take 469 away from 470, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
If we divide 10 by 67, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 9567.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
67 can be fit into 100 1 times, resulting in a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 9567.01
If we subtract 67 from 100, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
67 can be fit into 330 4 times, resulting in a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 9567.014
Subtracting 268 from 330 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.

Let's proceed to step 10:
If we divide 620 by 67, we get 9 and a remainder of 17.
The next digit of our result is 9. 
Result so far: 9567.0149
The remainder is 17 after subtracting 603 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 11:
When dividing 170 by 67, we get 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 9567.01492
Subtracting 134 from 170 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.

Moving on to step 12:
67 can be fit into 360 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 9567.014925
The remainder is 25 after subtracting 335 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 13:
250 divided by 67 is 3 with a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 9567.0149253
Subtract 201 from 250 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 14:
67 goes into 490 7 times with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 9567.01492537
The remainder is 21 after subtracting 469 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 9567.01492537 with a remaining 2.1e-08.
