We're dividing 45115198 by 144 
Our goal is to divide 45115198 by 144.

Moving on to step 1:
144 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 144

Advancing to step 2:
When dividing 45 by 144, we get 0 with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 144

Advancing to step 3:
144 can be fit into 451 3 times, resulting in a remainder of 19.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 19 after subtracting 432 from 451.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 144

Moving on to step 4:
The number 144 fits into 191 1 times, leaving a remainder of 47.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 144 from 191 to get 47.
Bring next digit (5) of the dividend behind the 47 and repeat the process: 475 / 144

On to step 5:
475 divided by 144 is 3 with a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 313.0
If we take 432 away from 475, we end up with 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 144

Step 6:
144 can be fit into 431 2 times, resulting in a remainder of 143.
Put 2 as the next digit of the answer. 
Result so far: 3132.0
Subtract 288 from 431 to get 143.
Fetch the next digit (9) from the dividend, attach it to 143 and continue: 1439 / 144

Going ahead to step 7:
144 can be fit into 1439 9 times, resulting in a remainder of 143.
The number 9 becomes the next digit in our result. 
Result so far: 31329.0
The remainder is 143 after subtracting 1296 from 1439.
Append the next digit (8) from the dividend to 143 and continue with: 1438 / 144

Moving on to step 8:
If we divide 1438 by 144, we get 9 and a remainder of 142.
The next digit of our result is 9. 
Result so far: 313299.0
Subtract 1296 from 1438 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 9:
1420 divided by 144 is 9 with a remainder of 124.
Record the quotient 9 as the next digit in the result. 
Result so far: 313299.9
Subtract 1296 from 1420 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 10:
When dividing 1240 by 144, we get 8 with a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 313299.98
The remainder is 88 after subtracting 1152 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 11:
The number 144 fits into 880 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 313299.986
The remainder is 16 after subtracting 864 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
If we divide 160 by 144, we get 1 and a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 313299.9861
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
144 goes into 160 1 times with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 313299.98611
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 313299.98611 and a remainder of 1.6e-05.
