We look at the division of 47579703 by 643 
Let's see how many times 643 fits into 47579703.

Moving on to step 1:
When dividing 4 by 643, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 643

Step 2:
643 can be fit into 47 0 times, resulting in a remainder of 47.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 47, we get 47.
Bring next digit (5) of the dividend behind the 47 and repeat the process: 475 / 643

Advancing to step 3:
475 divided by 643 is 0 with a remainder of 475.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 475 and we're left with 475.
Take the next digit (7) from the dividend and append it to 475, then repeat: 4757 / 643

Step 4:
If we divide 4757 by 643, we get 7 and a remainder of 256.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 4501 from 4757 and we're left with 256.
Fetch the next digit (9) from the dividend, attach it to 256 and continue: 2569 / 643

Let's proceed to step 5:
643 can be fit into 2569 3 times, resulting in a remainder of 640.
The next digit of our result is 3. 
Result so far: 73.0
Deduct 1929 from 2569 and we're left with 640.
Bring next digit (7) of the dividend behind the 640 and repeat the process: 6407 / 643

On to step 6:
643 goes into 6407 9 times with a remainder of 620.
Put 9 as the next digit of the answer. 
Result so far: 739.0
Subtracting 5787 from 6407 leaves us with 620.
Bring next digit (0) of the dividend behind the 620 and repeat the process: 6200 / 643

Going ahead to step 7:
643 goes into 6200 9 times with a remainder of 413.
The next digit of our result is 9. 
Result so far: 7399.0
The remainder is 413 after subtracting 5787 from 6200.
Bring next digit (3) of the dividend behind the 413 and repeat the process: 4133 / 643

Moving on to step 8:
643 can be fit into 4133 6 times, resulting in a remainder of 275.
Write down 6 as next digit of the result. 
Result so far: 73996.0
If we subtract 3858 from 4133, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 9:
2750 divided by 643 is 4 with a remainder of 178.
The next digit of our result is 4. 
Result so far: 73996.4
Subtracting 2572 from 2750 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 10:
643 can be fit into 1780 2 times, resulting in a remainder of 494.
The next digit of our result is 2. 
Result so far: 73996.42
If we subtract 1286 from 1780, we get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Going ahead to step 11:
643 goes into 4940 7 times with a remainder of 439.
The number 7 becomes the next digit in our result. 
Result so far: 73996.427
If we take 4501 away from 4940, we end up with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Let's proceed to step 12:
4390 divided by 643 is 6 with a remainder of 532.
The number 6 becomes the next digit in our result. 
Result so far: 73996.4276
If we subtract 3858 from 4390, we get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

On to step 13:
The number 643 fits into 5320 8 times, leaving a remainder of 176.
Put 8 as the next digit of the answer. 
Result so far: 73996.42768
Deduct 5144 from 5320 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 14:
643 can be fit into 1760 2 times, resulting in a remainder of 474.
Put 2 as the next digit of the answer. 
Result so far: 73996.427682
Deduct 1286 from 1760 and we're left with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Moving on to step 15:
643 can be fit into 4740 7 times, resulting in a remainder of 239.
The next digit of our result is 7. 
Result so far: 73996.4276827
If we subtract 4501 from 4740, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Going ahead to step 16:
If we divide 2390 by 643, we get 3 and a remainder of 461.
Use 3 as the next digit of our solution. 
Result so far: 73996.42768273
The remainder is 461 after subtracting 1929 from 2390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

The final result is 73996.42768273 with a remainder of 4.61e-07.
