31561067 ÷ 287 
Our goal is to divide 31561067 by 287.

Moving on to step 1:
3 divided by 287 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 287

On to step 2:
The number 287 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 287

Let's proceed to step 3:
If we divide 315 by 287, we get 1 and a remainder of 28.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 28 after subtracting 287 from 315.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 287

Advancing to step 4:
The number 287 fits into 286 0 times, leaving a remainder of 286.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 286 to get 286.
Bring next digit (1) of the dividend behind the 286 and repeat the process: 2861 / 287

Let's proceed to step 5:
If we divide 2861 by 287, we get 9 and a remainder of 278.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
Subtract 2583 from 2861 to get 278.
Append the next digit (0) from the dividend to 278 and continue with: 2780 / 287

Going ahead to step 6:
The number 287 fits into 2780 9 times, leaving a remainder of 197.
The next digit of our result is 9. 
Result so far: 1099.0
Deduct 2583 from 2780 and we're left with 197.
Append the next digit (6) from the dividend to 197 and continue with: 1976 / 287

Moving on to step 7:
287 goes into 1976 6 times with a remainder of 254.
Use 6 as the next digit of our solution. 
Result so far: 10996.0
Subtracting 1722 from 1976 leaves us with 254.
Include the next digit (7) from the dividend after 254, then repeat: 2547 / 287

On to step 8:
If we divide 2547 by 287, we get 8 and a remainder of 251.
Put 8 as the next digit of the answer. 
Result so far: 109968.0
The remainder is 251 after subtracting 2296 from 2547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Moving on to step 9:
When dividing 2510 by 287, we get 8 with a remainder of 214.
Record the quotient 8 as the next digit in the result. 
Result so far: 109968.8
Subtract 2296 from 2510 to get 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 10:
287 can be fit into 2140 7 times, resulting in a remainder of 131.
The next digit of our result is 7. 
Result so far: 109968.87
Deduct 2009 from 2140 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 11:
If we divide 1310 by 287, we get 4 and a remainder of 162.
The next digit of our result is 4. 
Result so far: 109968.874
Deduct 1148 from 1310 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 12:
The number 287 fits into 1620 5 times, leaving a remainder of 185.
The next digit of our result is 5. 
Result so far: 109968.8745
Deduct 1435 from 1620 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 13:
287 can be fit into 1850 6 times, resulting in a remainder of 128.
Put 6 as the next digit of the answer. 
Result so far: 109968.87456
If we take 1722 away from 1850, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 14:
When dividing 1280 by 287, we get 4 with a remainder of 132.
The number 4 becomes the next digit in our result. 
Result so far: 109968.874564
If we subtract 1148 from 1280, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 15:
When dividing 1320 by 287, we get 4 with a remainder of 172.
Write down 4 as next digit of the result. 
Result so far: 109968.8745644
Subtract 1148 from 1320 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

After the division, we end up with 109968.8745644 and a remainder of 1.72e-06.
