We divide 640268 by 89
We're looking to find how many times 89 goes into 640268.

Moving on to step 1:
If we divide 6 by 89, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 89

Moving on to step 2:
89 can be fit into 64 0 times, resulting in a remainder of 64.
Use 0 as the next digit of our solution. 
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 / 89

On to step 3:
89 goes into 640 7 times with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 623 away from 640, we end up with 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 89

Let's proceed to step 4:
89 goes into 172 1 times with a remainder of 83.
Write down 1 as next digit of the result. 
Result so far: 71.0
The remainder is 83 after subtracting 89 from 172.
Take the next digit (6) from the dividend and append it to 83, then repeat: 836 / 89

Step 5:
When dividing 836 by 89, we get 9 with a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 719.0
If we take 801 away from 836, we end up with 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 89

On to step 6:
The number 89 fits into 358 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 7194.0
Deduct 356 from 358 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
89 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 7194.0
Subtract 0 from 20 to get 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 8:
89 can be fit into 200 2 times, resulting in a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 7194.02
The remainder is 22 after subtracting 178 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
89 goes into 220 2 times with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 7194.022
Deduct 178 from 220 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.

Our division results in 7194.022 with a remaining 0.0042.
