We divide 3953516 by 400
Let's see how many times 400 fits into 3953516.

Moving on to step 1:
If we divide 3 by 400, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 400

Let's proceed to step 2:
39 divided by 400 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 400

On to step 3:
When dividing 395 by 400, we get 0 with a remainder of 395.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 395 and we're left with 395.
Bring next digit (3) of the dividend behind the 395 and repeat the process: 3953 / 400

Step 4:
400 goes into 3953 9 times with a remainder of 353.
The next digit of our result is 9. 
Result so far: 9.0
If we take 3600 away from 3953, we end up with 353.
Include the next digit (5) from the dividend after 353, then repeat: 3535 / 400

Let's proceed to step 5:
3535 divided by 400 is 8 with a remainder of 335.
Write down 8 as next digit of the result. 
Result so far: 98.0
Deduct 3200 from 3535 and we're left with 335.
Take the next digit (1) from the dividend and append it to 335, then repeat: 3351 / 400

Advancing to step 6:
400 goes into 3351 8 times with a remainder of 151.
The next digit of our result is 8. 
Result so far: 988.0
Subtract 3200 from 3351 to get 151.
Bring next digit (6) of the dividend behind the 151 and repeat the process: 1516 / 400

Advancing to step 7:
400 can be fit into 1516 3 times, resulting in a remainder of 316.
The next digit of our result is 3. 
Result so far: 9883.0
Subtract 1200 from 1516 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Going ahead to step 8:
The number 400 fits into 3160 7 times, leaving a remainder of 360.
Record the quotient 7 as the next digit in the result. 
Result so far: 9883.7
Subtract 2800 from 3160 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 9:
400 goes into 3600 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9883.79
If we subtract 3600 from 3600, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
If we divide 0 by 400, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9883.79
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
400 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9883.79
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 9883.79 with a remaining 0.0.
