We look at the division of 357545 by 31 
We're looking to find how many times 31 goes into 357545.

On to step 1:
31 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 31

Going ahead to step 2:
31 can be fit into 35 1 times, resulting in a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 4 after subtracting 31 from 35.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 31

Moving on to step 3:
The number 31 fits into 47 1 times, leaving a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 31 from 47 and we're left with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 31

Advancing to step 4:
31 goes into 165 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 115.0
Subtract 155 from 165 to get 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 31

Moving on to step 5:
If we divide 104 by 31, we get 3 and a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 1153.0
Deduct 93 from 104 and we're left with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 31

Going ahead to step 6:
When dividing 115 by 31, we get 3 with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 11533.0
Subtracting 93 from 115 leaves us with 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 7:
When dividing 220 by 31, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 11533.7
The remainder is 3 after subtracting 217 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
31 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 11533.7
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
If we divide 300 by 31, we get 9 and a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 11533.709
If we subtract 279 from 300, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
When dividing 210 by 31, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 11533.7096
Subtract 186 from 210 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
If we divide 240 by 31, we get 7 and a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 11533.70967
If we subtract 217 from 240, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 12:
31 goes into 230 7 times with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 11533.709677
If we take 217 away from 230, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 11533.709677, with a leftover of 1.3e-06.
