We're dividing 643948 by 74 
We want to figure out the number of times 643948 can be divided by 74.

Let's proceed to step 1:
74 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 74

On to step 2:
64 divided by 74 is 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Append the next digit (3) from the dividend to 64 and continue with: 643 / 74

On to step 3:
When dividing 643 by 74, we get 8 with a remainder of 51.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 592 from 643, we get 51.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 74

Let's proceed to step 4:
When dividing 519 by 74, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 87.0
If we take 518 away from 519, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 74

Let's proceed to step 5:
74 can be fit into 14 0 times, resulting in a remainder of 14.
The next digit of our result is 0. 
Result so far: 870.0
Subtracting 0 from 14 leaves us with 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 74

Advancing to step 6:
If we divide 148 by 74, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 8702.0
If we subtract 148 from 148, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
0 divided by 74 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8702.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 74 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8702.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 8702.0 with a balance of 0.0.
