We're dividing 15145510 by 202 
We want to figure out the number of times 15145510 can be divided by 202.

Step 1:
The number 202 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 202

Step 2:
The number 202 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 202

Let's proceed to step 3:
202 can be fit into 151 0 times, resulting in a remainder of 151.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 151 to get 151.
Take the next digit (4) from the dividend and append it to 151, then repeat: 1514 / 202

Moving on to step 4:
The number 202 fits into 1514 7 times, leaving a remainder of 100.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 100 after subtracting 1414 from 1514.
Grab the next digit (5) from the dividend, add it to 100, then carry on: 1005 / 202

Step 5:
202 can be fit into 1005 4 times, resulting in a remainder of 197.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Subtracting 808 from 1005 leaves us with 197.
Take the next digit (5) from the dividend and append it to 197, then repeat: 1975 / 202

Step 6:
The number 202 fits into 1975 9 times, leaving a remainder of 157.
Write down 9 as next digit of the result. 
Result so far: 749.0
Subtracting 1818 from 1975 leaves us with 157.
Take the next digit (1) from the dividend and append it to 157, then repeat: 1571 / 202

Let's proceed to step 7:
202 goes into 1571 7 times with a remainder of 157.
Record the quotient 7 as the next digit in the result. 
Result so far: 7497.0
The remainder is 157 after subtracting 1414 from 1571.
Include the next digit (0) from the dividend after 157, then repeat: 1570 / 202

Advancing to step 8:
202 can be fit into 1570 7 times, resulting in a remainder of 156.
Put 7 as the next digit of the answer. 
Result so far: 74977.0
If we take 1414 away from 1570, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 9:
1560 divided by 202 is 7 with a remainder of 146.
Write down 7 as next digit of the result. 
Result so far: 74977.7
Subtracting 1414 from 1560 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 10:
1460 divided by 202 is 7 with a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 74977.77
The remainder is 46 after subtracting 1414 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 74977.77, with a leftover of 0.046.
