640860 ÷ 74 
We want to divide 640860 by 74.

Step 1:
74 goes into 6 0 times 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.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 74

Let's proceed to step 2:
If we divide 64 by 74, we get 0 and a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 74

Moving on to step 3:
The number 74 fits into 640 8 times, leaving a remainder of 48.
The next digit of our result is 8. 
Result so far: 8.0
If we take 592 away from 640, we end up with 48.
Grab the next digit (8) from the dividend, add it to 48, then carry on: 488 / 74

Let's proceed to step 4:
74 can be fit into 488 6 times, resulting in a remainder of 44.
The next digit of our result is 6. 
Result so far: 86.0
The remainder is 44 after subtracting 444 from 488.
Include the next digit (6) from the dividend after 44, then repeat: 446 / 74

Let's proceed to step 5:
74 goes into 446 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 866.0
If we take 444 away from 446, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 74

Advancing to step 6:
74 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8660.0
If we subtract 0 from 20, we 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.

Let's proceed to step 7:
200 divided by 74 is 2 with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 8660.2
Deduct 148 from 200 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 8:
The number 74 fits into 520 7 times, leaving a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 8660.27
If we subtract 518 from 520, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
74 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 8660.27
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.

Moving on to step 10:
When dividing 200 by 74, we get 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 8660.2702
Subtract 148 from 200 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
If we divide 520 by 74, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 8660.27027
The remainder is 2 after subtracting 518 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
20 divided by 74 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8660.27027
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.

Moving on to step 13:
If we divide 200 by 74, we get 2 and a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 8660.2702702
Subtract 148 from 200 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 14:
When dividing 520 by 74, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 8660.27027027
Subtract 518 from 520 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 8660.27027027 with a balance of 2e-09.
