We look at the division of 72042720 by 159 
We want to figure out the number of times 72042720 can be divided by 159.

Step 1:
7 divided by 159 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 159

Advancing to step 2:
When dividing 72 by 159, we get 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Take the next digit (0) from the dividend and append it to 72, then repeat: 720 / 159

Moving on to step 3:
The number 159 fits into 720 4 times, leaving a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 636 away from 720, we end up with 84.
Bring next digit (4) of the dividend behind the 84 and repeat the process: 844 / 159

Moving on to step 4:
If we divide 844 by 159, we get 5 and a remainder of 49.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtract 795 from 844 to get 49.
Take the next digit (2) from the dividend and append it to 49, then repeat: 492 / 159

On to step 5:
If we divide 492 by 159, we get 3 and a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 453.0
The remainder is 15 after subtracting 477 from 492.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 159

Let's proceed to step 6:
If we divide 157 by 159, we get 0 and a remainder of 157.
The number 0 becomes the next digit in our result. 
Result so far: 4530.0
Deduct 0 from 157 and we're left with 157.
Grab the next digit (2) from the dividend, add it to 157, then carry on: 1572 / 159

Advancing to step 7:
159 can be fit into 1572 9 times, resulting in a remainder of 141.
Put 9 as the next digit of the answer. 
Result so far: 45309.0
Subtracting 1431 from 1572 leaves us with 141.
Append the next digit (0) from the dividend to 141 and continue with: 1410 / 159

Going ahead to step 8:
159 can be fit into 1410 8 times, resulting in a remainder of 138.
The number 8 becomes the next digit in our result. 
Result so far: 453098.0
Deduct 1272 from 1410 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 9:
The number 159 fits into 1380 8 times, leaving a remainder of 108.
Record the quotient 8 as the next digit in the result. 
Result so far: 453098.8
Deduct 1272 from 1380 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 10:
159 goes into 1080 6 times with a remainder of 126.
Put 6 as the next digit of the answer. 
Result so far: 453098.86
Subtract 954 from 1080 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 11:
159 goes into 1260 7 times with a remainder of 147.
Record the quotient 7 as the next digit in the result. 
Result so far: 453098.867
Subtracting 1113 from 1260 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Moving on to step 12:
1470 divided by 159 is 9 with a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 453098.8679
The remainder is 39 after subtracting 1431 from 1470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 13:
159 goes into 390 2 times with a remainder of 72.
The next digit of our result is 2. 
Result so far: 453098.86792
Deduct 318 from 390 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
159 can be fit into 720 4 times, resulting in a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 453098.867924
Deduct 636 from 720 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 15:
159 can be fit into 840 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 453098.8679245
Deduct 795 from 840 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 16:
450 divided by 159 is 2 with a remainder of 132.
Use 2 as the next digit of our solution. 
Result so far: 453098.86792452
The remainder is 132 after subtracting 318 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final result is 453098.86792452 with a remainder of 1.32e-07.
