31969 divided by 86 
We want to figure out the number of times 31969 can be divided by 86.

On to step 1:
If we divide 3 by 86, we get 0 and 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.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 86

Going ahead to step 2:
31 divided by 86 is 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 86

Going ahead to step 3:
The number 86 fits into 319 3 times, leaving a remainder of 61.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 258 from 319 and we're left with 61.
Grab the next digit (6) from the dividend, add it to 61, then carry on: 616 / 86

Going ahead to step 4:
616 divided by 86 is 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Subtracting 602 from 616 leaves us with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 86

Going ahead to step 5:
The number 86 fits into 149 1 times, leaving a remainder of 63.
Write down 1 as next digit of the result. 
Result so far: 371.0
Deduct 86 from 149 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 6:
The number 86 fits into 630 7 times, leaving a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 371.7
If we subtract 602 from 630, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
86 can be fit into 280 3 times, resulting in a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 371.73
Subtract 258 from 280 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
86 goes into 220 2 times with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 371.732
Subtract 172 from 220 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
480 divided by 86 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 371.7325
Subtracting 430 from 480 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
500 divided by 86 is 5 with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 371.73255
If we subtract 430 from 500, 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.

Our division results in 371.73255 with a remaining 7e-05.
