31544329 ÷ 261 
Our goal is to divide 31544329 by 261.

Going ahead to step 1:
261 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 261

Step 2:
261 can be fit into 31 0 times, resulting in a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 261

Moving on to step 3:
When dividing 315 by 261, we get 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 261 from 315, we get 54.
Take the next digit (4) from the dividend and append it to 54, then repeat: 544 / 261

Let's proceed to step 4:
544 divided by 261 is 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 522 from 544 and we're left with 22.
Fetch the next digit (4) from the dividend, attach it to 22 and continue: 224 / 261

Step 5:
If we divide 224 by 261, we get 0 and a remainder of 224.
Write down 0 as next digit of the result. 
Result so far: 120.0
If we subtract 0 from 224, we get 224.
Take the next digit (3) from the dividend and append it to 224, then repeat: 2243 / 261

Let's proceed to step 6:
When dividing 2243 by 261, we get 8 with a remainder of 155.
Put 8 as the next digit of the answer. 
Result so far: 1208.0
If we take 2088 away from 2243, we end up with 155.
Bring next digit (2) of the dividend behind the 155 and repeat the process: 1552 / 261

Step 7:
If we divide 1552 by 261, we get 5 and a remainder of 247.
The number 5 becomes the next digit in our result. 
Result so far: 12085.0
Subtract 1305 from 1552 to get 247.
Take the next digit (9) from the dividend and append it to 247, then repeat: 2479 / 261

Let's proceed to step 8:
261 can be fit into 2479 9 times, resulting in a remainder of 130.
Record the quotient 9 as the next digit in the result. 
Result so far: 120859.0
Deduct 2349 from 2479 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 9:
1300 divided by 261 is 4 with a remainder of 256.
Put 4 as the next digit of the answer. 
Result so far: 120859.4
If we subtract 1044 from 1300, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 10:
261 can be fit into 2560 9 times, resulting in a remainder of 211.
Record the quotient 9 as the next digit in the result. 
Result so far: 120859.49
Deduct 2349 from 2560 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Let's proceed to step 11:
The number 261 fits into 2110 8 times, leaving a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 120859.498
The remainder is 22 after subtracting 2088 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
When dividing 220 by 261, we get 0 with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 120859.498
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 13:
261 goes into 2200 8 times with a remainder of 112.
Put 8 as the next digit of the answer. 
Result so far: 120859.49808
If we take 2088 away from 2200, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 14:
1120 divided by 261 is 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 120859.498084
If we subtract 1044 from 1120, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 15:
261 goes into 760 2 times with a remainder of 238.
The number 2 becomes the next digit in our result. 
Result so far: 120859.4980842
The remainder is 238 after subtracting 522 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 16:
261 can be fit into 2380 9 times, resulting in a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 120859.49808429
The remainder is 31 after subtracting 2349 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

After the division, we end up with 120859.49808429 and a remainder of 3.1e-08.
