We look at the division of 31241532 by 900 
We want to divide 31241532 by 900.

Let's proceed to step 1:
When dividing 3 by 900, we get 0 with 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 (1) from the dividend, add it to 3, then carry on: 31 / 900

Moving on to step 2:
When dividing 31 by 900, we get 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 900

Moving on to step 3:
The number 900 fits into 312 0 times, leaving a remainder of 312.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 312 and we're left with 312.
Include the next digit (4) from the dividend after 312, then repeat: 3124 / 900

Advancing to step 4:
When dividing 3124 by 900, we get 3 with a remainder of 424.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 424 after subtracting 2700 from 3124.
Include the next digit (1) from the dividend after 424, then repeat: 4241 / 900

Let's proceed to step 5:
900 can be fit into 4241 4 times, resulting in a remainder of 641.
Put 4 as the next digit of the answer. 
Result so far: 34.0
If we take 3600 away from 4241, we end up with 641.
Append the next digit (5) from the dividend to 641 and continue with: 6415 / 900

On to step 6:
The number 900 fits into 6415 7 times, leaving a remainder of 115.
Put 7 as the next digit of the answer. 
Result so far: 347.0
Subtracting 6300 from 6415 leaves us with 115.
Append the next digit (3) from the dividend to 115 and continue with: 1153 / 900

Advancing to step 7:
If we divide 1153 by 900, we get 1 and a remainder of 253.
Use 1 as the next digit of our solution. 
Result so far: 3471.0
Deduct 900 from 1153 and we're left with 253.
Bring next digit (2) of the dividend behind the 253 and repeat the process: 2532 / 900

Let's proceed to step 8:
900 can be fit into 2532 2 times, resulting in a remainder of 732.
Record the quotient 2 as the next digit in the result. 
Result so far: 34712.0
Deduct 1800 from 2532 and we're left with 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Let's proceed to step 9:
900 can be fit into 7320 8 times, resulting in a remainder of 120.
Write down 8 as next digit of the result. 
Result so far: 34712.8
Deduct 7200 from 7320 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 10:
If we divide 1200 by 900, we get 1 and a remainder of 300.
The next digit of our result is 1. 
Result so far: 34712.81
If we take 900 away from 1200, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
900 goes into 3000 3 times with a remainder of 300.
Write down 3 as next digit of the result. 
Result so far: 34712.813
The remainder is 300 after subtracting 2700 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 12:
3000 divided by 900 is 3 with a remainder of 300.
Record the quotient 3 as the next digit in the result. 
Result so far: 34712.8133
Deduct 2700 from 3000 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 34712.8133 with a remainder of 0.003.
