3953144 ÷ 849 
We want to divide 3953144 by 849.

Advancing to step 1:
The number 849 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 849

Let's proceed to step 2:
The number 849 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (5) from the dividend, add it to 39, then carry on: 395 / 849

Going ahead to step 3:
When dividing 395 by 849, we get 0 with a remainder of 395.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 395, we get 395.
Fetch the next digit (3) from the dividend, attach it to 395 and continue: 3953 / 849

Advancing to step 4:
849 can be fit into 3953 4 times, resulting in a remainder of 557.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3396 away from 3953, we end up with 557.
Include the next digit (1) from the dividend after 557, then repeat: 5571 / 849

Let's proceed to step 5:
5571 divided by 849 is 6 with a remainder of 477.
Use 6 as the next digit of our solution. 
Result so far: 46.0
The remainder is 477 after subtracting 5094 from 5571.
Bring next digit (4) of the dividend behind the 477 and repeat the process: 4774 / 849

Moving on to step 6:
If we divide 4774 by 849, we get 5 and a remainder of 529.
Write down 5 as next digit of the result. 
Result so far: 465.0
Deduct 4245 from 4774 and we're left with 529.
Append the next digit (4) from the dividend to 529 and continue with: 5294 / 849

On to step 7:
The number 849 fits into 5294 6 times, leaving a remainder of 200.
The number 6 becomes the next digit in our result. 
Result so far: 4656.0
Deduct 5094 from 5294 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 8:
The number 849 fits into 2000 2 times, leaving a remainder of 302.
Use 2 as the next digit of our solution. 
Result so far: 4656.2
Subtracting 1698 from 2000 leaves us with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 9:
When dividing 3020 by 849, we get 3 with a remainder of 473.
Record the quotient 3 as the next digit in the result. 
Result so far: 4656.23
If we take 2547 away from 3020, we end up with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Advancing to step 10:
The number 849 fits into 4730 5 times, leaving a remainder of 485.
Record the quotient 5 as the next digit in the result. 
Result so far: 4656.235
Subtracting 4245 from 4730 leaves us with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Advancing to step 11:
If we divide 4850 by 849, we get 5 and a remainder of 605.
Write down 5 as next digit of the result. 
Result so far: 4656.2355
If we subtract 4245 from 4850, we get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

After the division, we end up with 4656.2355 and a remainder of 0.00605.
