We look at the division of 57975710 by 643 
Our goal is to divide 57975710 by 643.

Moving on to step 1:
When dividing 5 by 643, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 643

Step 2:
If we divide 57 by 643, we get 0 and a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Bring next digit (9) of the dividend behind the 57 and repeat the process: 579 / 643

Going ahead to step 3:
When dividing 579 by 643, we get 0 with a remainder of 579.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 579 after subtracting 0 from 579.
Append the next digit (7) from the dividend to 579 and continue with: 5797 / 643

Advancing to step 4:
The number 643 fits into 5797 9 times, leaving a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 5787 from 5797 leaves us with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 643

Moving on to step 5:
643 can be fit into 105 0 times, resulting in a remainder of 105.
Put 0 as the next digit of the answer. 
Result so far: 90.0
If we subtract 0 from 105, we get 105.
Bring next digit (7) of the dividend behind the 105 and repeat the process: 1057 / 643

Moving on to step 6:
If we divide 1057 by 643, we get 1 and a remainder of 414.
Use 1 as the next digit of our solution. 
Result so far: 901.0
Deduct 643 from 1057 and we're left with 414.
Fetch the next digit (1) from the dividend, attach it to 414 and continue: 4141 / 643

On to step 7:
The number 643 fits into 4141 6 times, leaving a remainder of 283.
Use 6 as the next digit of our solution. 
Result so far: 9016.0
The remainder is 283 after subtracting 3858 from 4141.
Bring next digit (0) of the dividend behind the 283 and repeat the process: 2830 / 643

Step 8:
When dividing 2830 by 643, we get 4 with a remainder of 258.
Use 4 as the next digit of our solution. 
Result so far: 90164.0
Deduct 2572 from 2830 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 9:
When dividing 2580 by 643, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 90164.4
Subtract 2572 from 2580 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
80 divided by 643 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 90164.4
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
800 divided by 643 is 1 with a remainder of 157.
Put 1 as the next digit of the answer. 
Result so far: 90164.401
Subtracting 643 from 800 leaves us with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 12:
1570 divided by 643 is 2 with a remainder of 284.
The number 2 becomes the next digit in our result. 
Result so far: 90164.4012
Subtract 1286 from 1570 to 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.

Going ahead to step 13:
643 goes into 2840 4 times with a remainder of 268.
The next digit of our result is 4. 
Result so far: 90164.40124
The remainder is 268 after subtracting 2572 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 14:
643 goes into 2680 4 times with a remainder of 108.
The number 4 becomes the next digit in our result. 
Result so far: 90164.401244
Subtract 2572 from 2680 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final outcome is 90164.401244, with a leftover of 1.08e-05.
