We're dividing 55572075 by 643 
Let's see how many times 643 fits into 55572075.

Step 1:
643 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 643

On to step 2:
When dividing 55 by 643, we get 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Bring next digit (5) of the dividend behind the 55 and repeat the process: 555 / 643

Let's proceed to step 3:
643 can be fit into 555 0 times, resulting in a remainder of 555.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 555, we end up with 555.
Bring next digit (7) of the dividend behind the 555 and repeat the process: 5557 / 643

Let's proceed to step 4:
The number 643 fits into 5557 8 times, leaving a remainder of 413.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 5144 away from 5557, we end up with 413.
Fetch the next digit (2) from the dividend, attach it to 413 and continue: 4132 / 643

Step 5:
643 goes into 4132 6 times with a remainder of 274.
The next digit of our result is 6. 
Result so far: 86.0
The remainder is 274 after subtracting 3858 from 4132.
Grab the next digit (0) from the dividend, add it to 274, then carry on: 2740 / 643

Going ahead to step 6:
The number 643 fits into 2740 4 times, leaving a remainder of 168.
Write down 4 as next digit of the result. 
Result so far: 864.0
If we take 2572 away from 2740, we end up with 168.
Take the next digit (7) from the dividend and append it to 168, then repeat: 1687 / 643

Moving on to step 7:
643 can be fit into 1687 2 times, resulting in a remainder of 401.
Put 2 as the next digit of the answer. 
Result so far: 8642.0
If we take 1286 away from 1687, we end up with 401.
Take the next digit (5) from the dividend and append it to 401, then repeat: 4015 / 643

Going ahead to step 8:
643 can be fit into 4015 6 times, resulting in a remainder of 157.
Put 6 as the next digit of the answer. 
Result so far: 86426.0
If we subtract 3858 from 4015, we get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 9:
1570 divided by 643 is 2 with a remainder of 284.
Put 2 as the next digit of the answer. 
Result so far: 86426.2
If we subtract 1286 from 1570, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 10:
643 can be fit into 2840 4 times, resulting in a remainder of 268.
Use 4 as the next digit of our solution. 
Result so far: 86426.24
Deduct 2572 from 2840 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Let's proceed to step 11:
If we divide 2680 by 643, we get 4 and a remainder of 108.
Use 4 as the next digit of our solution. 
Result so far: 86426.244
Subtracting 2572 from 2680 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

In conclusion, the division gives 86426.244 with a balance of 0.0108.
