Let's divide 3950251 by 261
Our goal is to divide 3950251 by 261.

Let's proceed to step 1:
If we divide 3 by 261, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 261

Going ahead to step 2:
If we divide 39 by 261, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 261

Advancing to step 3:
If we divide 395 by 261, we get 1 and a remainder of 134.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 261 from 395 and we're left with 134.
Grab the next digit (0) from the dividend, add it to 134, then carry on: 1340 / 261

Moving on to step 4:
261 goes into 1340 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 1305 from 1340 leaves us with 35.
Append the next digit (2) from the dividend to 35 and continue with: 352 / 261

Advancing to step 5:
The number 261 fits into 352 1 times, leaving a remainder of 91.
Write down 1 as next digit of the result. 
Result so far: 151.0
If we take 261 away from 352, we end up with 91.
Append the next digit (5) from the dividend to 91 and continue with: 915 / 261

Moving on to step 6:
If we divide 915 by 261, we get 3 and a remainder of 132.
Put 3 as the next digit of the answer. 
Result so far: 1513.0
If we subtract 783 from 915, we get 132.
Grab the next digit (1) from the dividend, add it to 132, then carry on: 1321 / 261

Going ahead to step 7:
If we divide 1321 by 261, we get 5 and a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 15135.0
Subtracting 1305 from 1321 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
When dividing 160 by 261, we get 0 with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 15135.0
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 9:
261 goes into 1600 6 times with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 15135.06
The remainder is 34 after subtracting 1566 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
261 can be fit into 340 1 times, resulting in a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 15135.061
If we take 261 away from 340, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 11:
261 can be fit into 790 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 15135.0613
Subtract 783 from 790 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
If we divide 70 by 261, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 15135.0613
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 13:
261 can be fit into 700 2 times, resulting in a remainder of 178.
Put 2 as the next digit of the answer. 
Result so far: 15135.061302
If we subtract 522 from 700, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 14:
If we divide 1780 by 261, we get 6 and a remainder of 214.
The next digit of our result is 6. 
Result so far: 15135.0613026
Subtracting 1566 from 1780 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 15:
The number 261 fits into 2140 8 times, leaving a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 15135.06130268
If we take 2088 away from 2140, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 15135.06130268 with a remainder of 5.2e-08.
