We look at the division of 57515597 by 225 
Let's see how many times 225 fits into 57515597.

Let's proceed to step 1:
When dividing 5 by 225, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 225

Moving on to step 2:
The number 225 fits into 57 0 times, leaving a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Grab the next digit (5) from the dividend, add it to 57, then carry on: 575 / 225

Advancing to step 3:
The number 225 fits into 575 2 times, leaving a remainder of 125.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 450 from 575 leaves us with 125.
Grab the next digit (1) from the dividend, add it to 125, then carry on: 1251 / 225

Going ahead to step 4:
When dividing 1251 by 225, we get 5 with a remainder of 126.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we take 1125 away from 1251, we end up with 126.
Append the next digit (5) from the dividend to 126 and continue with: 1265 / 225

Advancing to step 5:
225 can be fit into 1265 5 times, resulting in a remainder of 140.
The next digit of our result is 5. 
Result so far: 255.0
If we take 1125 away from 1265, we end up with 140.
Append the next digit (5) from the dividend to 140 and continue with: 1405 / 225

Let's proceed to step 6:
When dividing 1405 by 225, we get 6 with a remainder of 55.
Record the quotient 6 as the next digit in the result. 
Result so far: 2556.0
If we subtract 1350 from 1405, we get 55.
Append the next digit (9) from the dividend to 55 and continue with: 559 / 225

Let's proceed to step 7:
225 can be fit into 559 2 times, resulting in a remainder of 109.
Use 2 as the next digit of our solution. 
Result so far: 25562.0
Subtracting 450 from 559 leaves us with 109.
Bring next digit (7) of the dividend behind the 109 and repeat the process: 1097 / 225

Step 8:
1097 divided by 225 is 4 with a remainder of 197.
The number 4 becomes the next digit in our result. 
Result so far: 255624.0
Deduct 900 from 1097 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Step 9:
The number 225 fits into 1970 8 times, leaving a remainder of 170.
Put 8 as the next digit of the answer. 
Result so far: 255624.8
Subtracting 1800 from 1970 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 10:
When dividing 1700 by 225, we get 7 with a remainder of 125.
Put 7 as the next digit of the answer. 
Result so far: 255624.87
Subtract 1575 from 1700 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 11:
If we divide 1250 by 225, we get 5 and a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 255624.875
If we take 1125 away from 1250, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 12:
1250 divided by 225 is 5 with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 255624.8755
Subtract 1125 from 1250 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Our division results in 255624.8755 with a remaining 0.00125.
