We look at the division of 72901737 by 78 
Let's see how many times 78 fits into 72901737.

Step 1:
The number 78 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 78

Let's proceed to step 2:
78 goes into 72 0 times with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Bring next digit (9) of the dividend behind the 72 and repeat the process: 729 / 78

Advancing to step 3:
78 goes into 729 9 times with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 702 from 729 and we're left with 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 78

Let's proceed to step 4:
When dividing 270 by 78, we get 3 with a remainder of 36.
The next digit of our result is 3. 
Result so far: 93.0
Subtract 234 from 270 to get 36.
Include the next digit (1) from the dividend after 36, then repeat: 361 / 78

Moving on to step 5:
78 goes into 361 4 times with a remainder of 49.
Write down 4 as next digit of the result. 
Result so far: 934.0
Deduct 312 from 361 and we're left with 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 78

Moving on to step 6:
78 goes into 497 6 times with a remainder of 29.
The next digit of our result is 6. 
Result so far: 9346.0
If we subtract 468 from 497, we get 29.
Take the next digit (3) from the dividend and append it to 29, then repeat: 293 / 78

On to step 7:
The number 78 fits into 293 3 times, leaving a remainder of 59.
The number 3 becomes the next digit in our result. 
Result so far: 93463.0
The remainder is 59 after subtracting 234 from 293.
Take the next digit (7) from the dividend and append it to 59, then repeat: 597 / 78

Going ahead to step 8:
597 divided by 78 is 7 with a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 934637.0
Subtracting 546 from 597 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 9:
If we divide 510 by 78, we get 6 and a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 934637.6
If we take 468 away from 510, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
420 divided by 78 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 934637.65
Deduct 390 from 420 and we're left 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.

Step 11:
The number 78 fits into 300 3 times, leaving a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 934637.653
Subtract 234 from 300 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 12:
The number 78 fits into 660 8 times, leaving a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 934637.6538
If we take 624 away from 660, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
78 can be fit into 360 4 times, resulting in a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 934637.65384
If we subtract 312 from 360, 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.

Let's proceed to step 14:
78 can be fit into 480 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 934637.653846
Deduct 468 from 480 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 15:
If we divide 120 by 78, we get 1 and a remainder of 42.
The next digit of our result is 1. 
Result so far: 934637.6538461
Deduct 78 from 120 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 16:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 934637.65384615
The remainder is 30 after subtracting 390 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 934637.65384615 and a remainder of 3e-08.
