47747812 ÷ 643 
We want to divide 47747812 by 643.

On to step 1:
The number 643 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 643

Let's proceed to step 2:
When dividing 47 by 643, we get 0 with a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 47 and we're left with 47.
Bring next digit (7) of the dividend behind the 47 and repeat the process: 477 / 643

Advancing to step 3:
643 goes into 477 0 times with a remainder of 477.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 477, we get 477.
Bring next digit (4) of the dividend behind the 477 and repeat the process: 4774 / 643

Advancing to step 4:
4774 divided by 643 is 7 with a remainder of 273.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 4501 from 4774 leaves us with 273.
Bring next digit (7) of the dividend behind the 273 and repeat the process: 2737 / 643

Step 5:
When dividing 2737 by 643, we get 4 with a remainder of 165.
Use 4 as the next digit of our solution. 
Result so far: 74.0
The remainder is 165 after subtracting 2572 from 2737.
Grab the next digit (8) from the dividend, add it to 165, then carry on: 1658 / 643

On to step 6:
643 can be fit into 1658 2 times, resulting in a remainder of 372.
Record the quotient 2 as the next digit in the result. 
Result so far: 742.0
If we subtract 1286 from 1658, we get 372.
Bring next digit (1) of the dividend behind the 372 and repeat the process: 3721 / 643

Moving on to step 7:
3721 divided by 643 is 5 with a remainder of 506.
Use 5 as the next digit of our solution. 
Result so far: 7425.0
Subtracting 3215 from 3721 leaves us with 506.
Grab the next digit (2) from the dividend, add it to 506, then carry on: 5062 / 643

Let's proceed to step 8:
643 goes into 5062 7 times with a remainder of 561.
Use 7 as the next digit of our solution. 
Result so far: 74257.0
Deduct 4501 from 5062 and we're left with 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Advancing to step 9:
When dividing 5610 by 643, we get 8 with a remainder of 466.
Record the quotient 8 as the next digit in the result. 
Result so far: 74257.8
Deduct 5144 from 5610 and we're left with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Step 10:
The number 643 fits into 4660 7 times, leaving a remainder of 159.
Record the quotient 7 as the next digit in the result. 
Result so far: 74257.87
If we take 4501 away from 4660, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Advancing to step 11:
When dividing 1590 by 643, we get 2 with a remainder of 304.
Write down 2 as next digit of the result. 
Result so far: 74257.872
If we take 1286 away from 1590, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 12:
When dividing 3040 by 643, we get 4 with a remainder of 468.
Write down 4 as next digit of the result. 
Result so far: 74257.8724
The remainder is 468 after subtracting 2572 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

On to step 13:
643 can be fit into 4680 7 times, resulting in a remainder of 179.
The number 7 becomes the next digit in our result. 
Result so far: 74257.87247
If we take 4501 away from 4680, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Moving on to step 14:
643 goes into 1790 2 times with a remainder of 504.
Put 2 as the next digit of the answer. 
Result so far: 74257.872472
If we subtract 1286 from 1790, we get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 15:
5040 divided by 643 is 7 with a remainder of 539.
The number 7 becomes the next digit in our result. 
Result so far: 74257.8724727
Subtracting 4501 from 5040 leaves us with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Step 16:
643 goes into 5390 8 times with a remainder of 246.
Write down 8 as next digit of the result. 
Result so far: 74257.87247278
If we take 5144 away from 5390, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

The quotient of the division is 74257.87247278, and the remainder is 2.46e-07.
