153770 ÷ 31 
We want to figure out the number of times 153770 can be divided by 31.

Going ahead to step 1:
When dividing 1 by 31, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 31

Going ahead to step 2:
31 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 31

On to step 3:
If we divide 153 by 31, we get 4 and a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 124 from 153, we get 29.
Bring next digit (7) of the dividend behind the 29 and repeat the process: 297 / 31

Step 4:
When dividing 297 by 31, we get 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we subtract 279 from 297, we get 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 31

On to step 5:
187 divided by 31 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 496.0
If we subtract 186 from 187, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 31

Let's proceed to step 6:
When dividing 10 by 31, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 4960.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
100 divided by 31 is 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 4960.3
Subtracting 93 from 100 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 8:
The number 31 fits into 70 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 4960.32
Subtract 62 from 70 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
When dividing 80 by 31, we get 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 4960.322
Subtract 62 from 80 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 4960.322, and the remainder is 0.0018.
