We look at the division of 435570 by 31 
We want to figure out the number of times 435570 can be divided by 31.

On to step 1:
4 divided by 31 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 31

Moving on to step 2:
The number 31 fits into 43 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 31 from 43 leaves us with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 31

Moving on to step 3:
If we divide 125 by 31, we get 4 and a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 124 from 125, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 31

Step 4:
31 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 140.0
Subtracting 0 from 15 leaves us with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 31

Step 5:
31 goes into 157 5 times with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 1405.0
The remainder is 2 after subtracting 155 from 157.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 31

Advancing to step 6:
When dividing 20 by 31, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 14050.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
If we divide 200 by 31, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 14050.6
The remainder is 14 after subtracting 186 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
When dividing 140 by 31, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 14050.64
The remainder is 16 after subtracting 124 from 140.
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 9:
31 goes into 160 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 14050.645
If we take 155 away from 160, we end up 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.

On to step 10:
When dividing 50 by 31, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 14050.6451
If we subtract 31 from 50, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 11:
31 can be fit into 190 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 14050.64516
If we subtract 186 from 190, we get 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 12:
40 divided by 31 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 14050.645161
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.

On to step 13:
The number 31 fits into 90 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 14050.6451612
If we take 62 away from 90, we end up 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.

Advancing to step 14:
280 divided by 31 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 14050.64516129
If we subtract 279 from 280, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 14050.64516129 with a remaining 1e-09.
