We're dividing 2974530 by 646 
Let's see how many times 646 fits into 2974530.

Moving on to step 1:
646 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 646

On to step 2:
646 can be fit into 29 0 times, resulting in a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Fetch the next digit (7) from the dividend, attach it to 29 and continue: 297 / 646

Going ahead to step 3:
When dividing 297 by 646, we get 0 with a remainder of 297.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 297 to get 297.
Include the next digit (4) from the dividend after 297, then repeat: 2974 / 646

Let's proceed to step 4:
646 can be fit into 2974 4 times, resulting in a remainder of 390.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 2584 from 2974, we get 390.
Fetch the next digit (5) from the dividend, attach it to 390 and continue: 3905 / 646

On to step 5:
If we divide 3905 by 646, we get 6 and a remainder of 29.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
If we subtract 3876 from 3905, we get 29.
Take the next digit (3) from the dividend and append it to 29, then repeat: 293 / 646

Going ahead to step 6:
646 can be fit into 293 0 times, resulting in a remainder of 293.
Put 0 as the next digit of the answer. 
Result so far: 460.0
Subtracting 0 from 293 leaves us with 293.
Fetch the next digit (0) from the dividend, attach it to 293 and continue: 2930 / 646

Going ahead to step 7:
646 goes into 2930 4 times with a remainder of 346.
The number 4 becomes the next digit in our result. 
Result so far: 4604.0
If we take 2584 away from 2930, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Step 8:
646 goes into 3460 5 times with a remainder of 230.
Put 5 as the next digit of the answer. 
Result so far: 4604.5
Subtracting 3230 from 3460 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 9:
The number 646 fits into 2300 3 times, leaving a remainder of 362.
Write down 3 as next digit of the result. 
Result so far: 4604.53
Subtracting 1938 from 2300 leaves us with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Going ahead to step 10:
When dividing 3620 by 646, we get 5 with a remainder of 390.
Write down 5 as next digit of the result. 
Result so far: 4604.535
Subtracting 3230 from 3620 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 11:
3900 divided by 646 is 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 4604.5356
Subtracting 3876 from 3900 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
When dividing 240 by 646, we get 0 with a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 4604.5356
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 13:
The number 646 fits into 2400 3 times, leaving a remainder of 462.
Put 3 as the next digit of the answer. 
Result so far: 4604.535603
Deduct 1938 from 2400 and we're left with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Moving on to step 14:
When dividing 4620 by 646, we get 7 with a remainder of 98.
Record the quotient 7 as the next digit in the result. 
Result so far: 4604.5356037
If we take 4522 away from 4620, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 15:
The number 646 fits into 980 1 times, leaving a remainder of 334.
Put 1 as the next digit of the answer. 
Result so far: 4604.53560371
Deduct 646 from 980 and we're left with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

The quotient of the division is 4604.53560371, and the remainder is 3.34e-07.
