We look at the division of 2759283 by 643 
Let's see how many times 643 fits into 2759283.

Going ahead to step 1:
When dividing 2 by 643, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 643

On to step 2:
If we divide 27 by 643, we get 0 and a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Bring next digit (5) of the dividend behind the 27 and repeat the process: 275 / 643

Advancing to step 3:
The number 643 fits into 275 0 times, leaving a remainder of 275.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 275 leaves us with 275.
Grab the next digit (9) from the dividend, add it to 275, then carry on: 2759 / 643

Moving on to step 4:
The number 643 fits into 2759 4 times, leaving a remainder of 187.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 187 after subtracting 2572 from 2759.
Bring next digit (2) of the dividend behind the 187 and repeat the process: 1872 / 643

Going ahead to step 5:
1872 divided by 643 is 2 with a remainder of 586.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we take 1286 away from 1872, we end up with 586.
Append the next digit (8) from the dividend to 586 and continue with: 5868 / 643

Moving on to step 6:
The number 643 fits into 5868 9 times, leaving a remainder of 81.
The next digit of our result is 9. 
Result so far: 429.0
Subtracting 5787 from 5868 leaves us with 81.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 643

Step 7:
The number 643 fits into 813 1 times, leaving a remainder of 170.
Write down 1 as next digit of the result. 
Result so far: 4291.0
Subtracting 643 from 813 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 8:
643 can be fit into 1700 2 times, resulting in a remainder of 414.
Use 2 as the next digit of our solution. 
Result so far: 4291.2
If we subtract 1286 from 1700, we get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Moving on to step 9:
The number 643 fits into 4140 6 times, leaving a remainder of 282.
Record the quotient 6 as the next digit in the result. 
Result so far: 4291.26
Deduct 3858 from 4140 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 10:
When dividing 2820 by 643, we get 4 with a remainder of 248.
The number 4 becomes the next digit in our result. 
Result so far: 4291.264
If we take 2572 away from 2820, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 11:
When dividing 2480 by 643, we get 3 with a remainder of 551.
Record the quotient 3 as the next digit in the result. 
Result so far: 4291.2643
Subtract 1929 from 2480 to get 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Let's proceed to step 12:
When dividing 5510 by 643, we get 8 with a remainder of 366.
Put 8 as the next digit of the answer. 
Result so far: 4291.26438
If we subtract 5144 from 5510, we get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Advancing to step 13:
If we divide 3660 by 643, we get 5 and a remainder of 445.
Put 5 as the next digit of the answer. 
Result so far: 4291.264385
If we subtract 3215 from 3660, we get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Advancing to step 14:
643 can be fit into 4450 6 times, resulting in a remainder of 592.
Write down 6 as next digit of the result. 
Result so far: 4291.2643856
If we subtract 3858 from 4450, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Step 15:
When dividing 5920 by 643, we get 9 with a remainder of 133.
The next digit of our result is 9. 
Result so far: 4291.26438569
If we subtract 5787 from 5920, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

After the division, we end up with 4291.26438569 and a remainder of 1.33e-07.
