We're dividing 71946936 by 144 
We want to divide 71946936 by 144.

Going ahead to step 1:
When dividing 7 by 144, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 144

Advancing to step 2:
If we divide 71 by 144, we get 0 and a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Include the next digit (9) from the dividend after 71, then repeat: 719 / 144

Going ahead to step 3:
144 goes into 719 4 times with a remainder of 143.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 576 away from 719, we end up with 143.
Append the next digit (4) from the dividend to 143 and continue with: 1434 / 144

Moving on to step 4:
When dividing 1434 by 144, we get 9 with a remainder of 138.
Put 9 as the next digit of the answer. 
Result so far: 49.0
If we subtract 1296 from 1434, we get 138.
Append the next digit (6) from the dividend to 138 and continue with: 1386 / 144

Let's proceed to step 5:
144 goes into 1386 9 times with a remainder of 90.
Write down 9 as next digit of the result. 
Result so far: 499.0
Deduct 1296 from 1386 and we're left with 90.
Bring next digit (9) of the dividend behind the 90 and repeat the process: 909 / 144

Going ahead to step 6:
If we divide 909 by 144, we get 6 and a remainder of 45.
The next digit of our result is 6. 
Result so far: 4996.0
Subtracting 864 from 909 leaves us with 45.
Take the next digit (3) from the dividend and append it to 45, then repeat: 453 / 144

Step 7:
The number 144 fits into 453 3 times, leaving a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 49963.0
Subtract 432 from 453 to get 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 144

On to step 8:
144 goes into 216 1 times with a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 499631.0
Subtract 144 from 216 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
The number 144 fits into 720 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 499631.5
Subtracting 720 from 720 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
The number 144 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 499631.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
When dividing 0 by 144, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 499631.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 499631.5 with a remaining 0.0.
