Let's divide 48714851 by 643
We want to divide 48714851 by 643.

Advancing to step 1:
When dividing 4 by 643, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 643

Moving on to step 2:
643 goes into 48 0 times with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 48 to get 48.
Include the next digit (7) from the dividend after 48, then repeat: 487 / 643

Let's proceed to step 3:
643 can be fit into 487 0 times, resulting in a remainder of 487.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 487 and we're left with 487.
Take the next digit (1) from the dividend and append it to 487, then repeat: 4871 / 643

Let's proceed to step 4:
4871 divided by 643 is 7 with a remainder of 370.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 4501 away from 4871, we end up with 370.
Grab the next digit (4) from the dividend, add it to 370, then carry on: 3704 / 643

Step 5:
643 goes into 3704 5 times with a remainder of 489.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Subtracting 3215 from 3704 leaves us with 489.
Grab the next digit (8) from the dividend, add it to 489, then carry on: 4898 / 643

Moving on to step 6:
4898 divided by 643 is 7 with a remainder of 397.
Use 7 as the next digit of our solution. 
Result so far: 757.0
If we subtract 4501 from 4898, we get 397.
Append the next digit (5) from the dividend to 397 and continue with: 3975 / 643

Going ahead to step 7:
643 goes into 3975 6 times with a remainder of 117.
Use 6 as the next digit of our solution. 
Result so far: 7576.0
Subtracting 3858 from 3975 leaves us with 117.
Bring next digit (1) of the dividend behind the 117 and repeat the process: 1171 / 643

Advancing to step 8:
643 goes into 1171 1 times with a remainder of 528.
Use 1 as the next digit of our solution. 
Result so far: 75761.0
If we take 643 away from 1171, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Step 9:
If we divide 5280 by 643, we get 8 and a remainder of 136.
Record the quotient 8 as the next digit in the result. 
Result so far: 75761.8
Subtracting 5144 from 5280 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 10:
When dividing 1360 by 643, we get 2 with a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 75761.82
If we take 1286 away from 1360, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 11:
If we divide 740 by 643, we get 1 and a remainder of 97.
The next digit of our result is 1. 
Result so far: 75761.821
Deduct 643 from 740 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 12:
When dividing 970 by 643, we get 1 with a remainder of 327.
Put 1 as the next digit of the answer. 
Result so far: 75761.8211
The remainder is 327 after subtracting 643 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

The final result is 75761.8211 with a remainder of 0.00327.
