We're dividing 55475139 by 144 
We want to figure out the number of times 55475139 can be divided by 144.

Let's proceed to step 1:
When dividing 5 by 144, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 144

On to step 2:
55 divided by 144 is 0 with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Grab the next digit (4) from the dividend, add it to 55, then carry on: 554 / 144

Let's proceed to step 3:
144 goes into 554 3 times with a remainder of 122.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 432 away from 554, we end up with 122.
Append the next digit (7) from the dividend to 122 and continue with: 1227 / 144

Advancing to step 4:
If we divide 1227 by 144, we get 8 and a remainder of 75.
Write down 8 as next digit of the result. 
Result so far: 38.0
Deduct 1152 from 1227 and we're left with 75.
Append the next digit (5) from the dividend to 75 and continue with: 755 / 144

Going ahead to step 5:
When dividing 755 by 144, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 385.0
Subtract 720 from 755 to get 35.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 144

Moving on to step 6:
If we divide 351 by 144, we get 2 and a remainder of 63.
Record the quotient 2 as the next digit in the result. 
Result so far: 3852.0
Subtract 288 from 351 to get 63.
Fetch the next digit (3) from the dividend, attach it to 63 and continue: 633 / 144

Step 7:
144 can be fit into 633 4 times, resulting in a remainder of 57.
The next digit of our result is 4. 
Result so far: 38524.0
If we take 576 away from 633, we end up with 57.
Include the next digit (9) from the dividend after 57, then repeat: 579 / 144

On to step 8:
When dividing 579 by 144, we get 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 385244.0
If we take 576 away from 579, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
If we divide 30 by 144, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 385244.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
144 can be fit into 300 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 385244.02
Subtract 288 from 300 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
If we divide 120 by 144, we get 0 and a remainder of 120.
The next digit of our result is 0. 
Result so far: 385244.02
Subtract 0 from 120 to get 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 12:
The number 144 fits into 1200 8 times, leaving a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 385244.0208
If we subtract 1152 from 1200, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 13:
The number 144 fits into 480 3 times, leaving a remainder of 48.
The next digit of our result is 3. 
Result so far: 385244.02083
Subtract 432 from 480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 14:
If we divide 480 by 144, we get 3 and a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 385244.020833
If we subtract 432 from 480, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 385244.020833 and a remainder of 4.8e-06.
