Result so far: 1.0
If we take 643 away from 997, we end up with 354.
Append the next digit (2) from the dividend to 354 and continue with: 3542 / 643

On to step 4:
When dividing 3542 by 643, we get 5 with a remainder of 327.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 3215 from 3542, we get 327.
Include the next digit (5) from the dividend after 327, then repeat: 3275 / 643

Advancing to step 5:
When dividing 3275 by 643, we get 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 155.0
Subtracting 3215 from 3275 leaves us with 60.
Fetch the next digit (3) from the dividend, attach it to 60 and continue: 603 / 643

Moving on to step 6:
603 divided by 643 is 0 with a remainder of 603.
The number 0 becomes the next digit in our result. 
Result so far: 1550.0
The remainder is 603 after subtracting 0 from 603.

Step 7:
643 goes into 6030 9 times with a remainder of 243.
Use 9 as the next digit of our solution. 
Result so far: 15509.0
If we take 5787 away from 6030, we end up with 243.
Grab the next digit (6) from the dividend, add it to 243, then carry on: 2436 / 643

Advancing to step 8:
The number 643 fits into 2436 3 times, leaving a remainder of 507.
Record the quotient 3 as the next digit in the result. 
Result so far: 155093.0
Subtract 1929 from 2436 to get 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Going ahead to step 9:
The number 643 fits into 5070 7 times, leaving a remainder of 569.
Record the quotient 7 as the next digit in the result. 
Result so far: 155093.7
Subtracting 4501 from 5070 leaves us with 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Going ahead to step 10:
643 goes into 5690 8 times with a remainder of 546.
The number 8 becomes the next digit in our result. 
Result so far: 155093.78
The remainder is 546 after subtracting 5144 from 5690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

On to step 11:
If we divide 5460 by 643, we get 8 and a remainder of 316.
Record the quotient 8 as the next digit in the result. 
Result so far: 155093.788
Subtract 5144 from 5460 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

In conclusion, the division gives 155093.788 with a balance of 0.0316.
