Let's divide 3951897 by 249
We're looking to find how many times 249 goes into 3951897.

Let's proceed to step 1:
3 divided by 249 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 249

Moving on to step 2:
When dividing 39 by 249, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 249

Going ahead to step 3:
395 divided by 249 is 1 with a remainder of 146.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 249 from 395 and we're left with 146.
Bring next digit (1) of the dividend behind the 146 and repeat the process: 1461 / 249

Moving on to step 4:
1461 divided by 249 is 5 with a remainder of 216.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 1245 from 1461, we get 216.
Append the next digit (8) from the dividend to 216 and continue with: 2168 / 249

Going ahead to step 5:
The number 249 fits into 2168 8 times, leaving a remainder of 176.
Write down 8 as next digit of the result. 
Result so far: 158.0
Deduct 1992 from 2168 and we're left with 176.
Take the next digit (9) from the dividend and append it to 176, then repeat: 1769 / 249

Let's proceed to step 6:
249 goes into 1769 7 times with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 1587.0
Subtract 1743 from 1769 to get 26.
Bring next digit (7) of the dividend behind the 26 and repeat the process: 267 / 249

Moving on to step 7:
249 can be fit into 267 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 15871.0
If we take 249 away from 267, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
249 can be fit into 180 0 times, resulting in a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 15871.0
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 9:
If we divide 1800 by 249, we get 7 and a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 15871.07
Subtracting 1743 from 1800 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 10:
249 can be fit into 570 2 times, resulting in a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 15871.072
Subtract 498 from 570 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
720 divided by 249 is 2 with a remainder of 222.
Use 2 as the next digit of our solution. 
Result so far: 15871.0722
If we subtract 498 from 720, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

After the division, we end up with 15871.0722 and a remainder of 0.00222.
