We divide 31394543 by 225
We want to divide 31394543 by 225.

Let's proceed to step 1:
225 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 225

Advancing to step 2:
When dividing 31 by 225, we get 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 225

Advancing to step 3:
If we divide 313 by 225, we get 1 and a remainder of 88.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 88 after subtracting 225 from 313.
Grab the next digit (9) from the dividend, add it to 88, then carry on: 889 / 225

Advancing to step 4:
When dividing 889 by 225, we get 3 with a remainder of 214.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 675 from 889 and we're left with 214.
Take the next digit (4) from the dividend and append it to 214, then repeat: 2144 / 225

Advancing to step 5:
The number 225 fits into 2144 9 times, leaving a remainder of 119.
Put 9 as the next digit of the answer. 
Result so far: 139.0
Subtracting 2025 from 2144 leaves us with 119.
Include the next digit (5) from the dividend after 119, then repeat: 1195 / 225

Advancing to step 6:
When dividing 1195 by 225, we get 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 1395.0
Subtract 1125 from 1195 to get 70.
Take the next digit (4) from the dividend and append it to 70, then repeat: 704 / 225

Moving on to step 7:
If we divide 704 by 225, we get 3 and a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 13953.0
If we subtract 675 from 704, we get 29.
Append the next digit (3) from the dividend to 29 and continue with: 293 / 225

Step 8:
If we divide 293 by 225, we get 1 and a remainder of 68.
The next digit of our result is 1. 
Result so far: 139531.0
If we subtract 225 from 293, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
680 divided by 225 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 139531.3
Subtracting 675 from 680 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.

Moving on to step 10:
225 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 139531.3
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
500 divided by 225 is 2 with a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 139531.302
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
The number 225 fits into 500 2 times, leaving a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 139531.3022
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 139531.3022 with a remainder of 0.0005.
