356936 ÷ 31 
Let's see how many times 31 fits into 356936.

Let's proceed to step 1:
When dividing 3 by 31, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 31

Going ahead to step 2:
If we divide 35 by 31, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 31 from 35 and we're left with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 31

On to step 3:
46 divided by 31 is 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 31 from 46 to get 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 31

Going ahead to step 4:
If we divide 159 by 31, we get 5 and a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
Subtract 155 from 159 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 31

On to step 5:
31 goes into 43 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1151.0
Subtract 31 from 43 to get 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 31

Let's proceed to step 6:
31 goes into 126 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 11514.0
Subtract 124 from 126 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
When dividing 20 by 31, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 11514.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
31 goes into 200 6 times with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 11514.06
Subtracting 186 from 200 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
31 can be fit into 140 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 11514.064
If we subtract 124 from 140, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
When dividing 160 by 31, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 11514.0645
Subtracting 155 from 160 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 11:
The number 31 fits into 50 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 11514.06451
Deduct 31 from 50 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 12:
If we divide 190 by 31, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 11514.064516
Subtracting 186 from 190 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
When dividing 40 by 31, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 11514.0645161
The remainder is 9 after subtracting 31 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
When dividing 90 by 31, we get 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 11514.06451612
Deduct 62 from 90 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 11514.06451612 with a remainder of 2.8e-08.
