Let's divide 3371655 by 643
We want to divide 3371655 by 643.

Moving on to step 1:
3 divided by 643 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 643

On to step 2:
The number 643 fits into 33 0 times, leaving a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Append the next digit (7) from the dividend to 33 and continue with: 337 / 643

Step 3:
The number 643 fits into 337 0 times, leaving a remainder of 337.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 337, we end up with 337.
Include the next digit (1) from the dividend after 337, then repeat: 3371 / 643

Moving on to step 4:
643 can be fit into 3371 5 times, resulting in a remainder of 156.
The next digit of our result is 5. 
Result so far: 5.0
If we take 3215 away from 3371, we end up with 156.
Take the next digit (6) from the dividend and append it to 156, then repeat: 1566 / 643

Let's proceed to step 5:
When dividing 1566 by 643, we get 2 with a remainder of 280.
The next digit of our result is 2. 
Result so far: 52.0
If we take 1286 away from 1566, we end up with 280.
Grab the next digit (5) from the dividend, add it to 280, then carry on: 2805 / 643

Let's proceed to step 6:
643 can be fit into 2805 4 times, resulting in a remainder of 233.
The next digit of our result is 4. 
Result so far: 524.0
Deduct 2572 from 2805 and we're left with 233.
Include the next digit (5) from the dividend after 233, then repeat: 2335 / 643

Moving on to step 7:
The number 643 fits into 2335 3 times, leaving a remainder of 406.
Record the quotient 3 as the next digit in the result. 
Result so far: 5243.0
If we subtract 1929 from 2335, we get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Going ahead to step 8:
If we divide 4060 by 643, we get 6 and a remainder of 202.
Put 6 as the next digit of the answer. 
Result so far: 5243.6
Subtract 3858 from 4060 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 9:
The number 643 fits into 2020 3 times, leaving a remainder of 91.
The next digit of our result is 3. 
Result so far: 5243.63
Subtracting 1929 from 2020 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 10:
643 goes into 910 1 times with a remainder of 267.
Record the quotient 1 as the next digit in the result. 
Result so far: 5243.631
Subtract 643 from 910 to get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Step 11:
643 goes into 2670 4 times with a remainder of 98.
The number 4 becomes the next digit in our result. 
Result so far: 5243.6314
The remainder is 98 after subtracting 2572 from 2670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 12:
When dividing 980 by 643, we get 1 with a remainder of 337.
The next digit of our result is 1. 
Result so far: 5243.63141
Deduct 643 from 980 and we're left with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Step 13:
If we divide 3370 by 643, we get 5 and a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 5243.631415
If we take 3215 away from 3370, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 14:
When dividing 1550 by 643, we get 2 with a remainder of 264.
Put 2 as the next digit of the answer. 
Result so far: 5243.6314152
The remainder is 264 after subtracting 1286 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 15:
2640 divided by 643 is 4 with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 5243.63141524
Subtract 2572 from 2640 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

After the division, we end up with 5243.63141524 and a remainder of 6.8e-08.
