Let's divide 72779617 by 578
We want to figure out the number of times 72779617 can be divided by 578.

Step 1:
The number 578 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 578

Moving on to step 2:
When dividing 72 by 578, we get 0 with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Take the next digit (7) from the dividend and append it to 72, then repeat: 727 / 578

On to step 3:
578 can be fit into 727 1 times, resulting in a remainder of 149.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 578 from 727 to get 149.
Fetch the next digit (7) from the dividend, attach it to 149 and continue: 1497 / 578

Advancing to step 4:
The number 578 fits into 1497 2 times, leaving a remainder of 341.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1156 from 1497 and we're left with 341.
Grab the next digit (9) from the dividend, add it to 341, then carry on: 3419 / 578

Going ahead to step 5:
3419 divided by 578 is 5 with a remainder of 529.
Use 5 as the next digit of our solution. 
Result so far: 125.0
If we subtract 2890 from 3419, we get 529.
Grab the next digit (6) from the dividend, add it to 529, then carry on: 5296 / 578

Step 6:
If we divide 5296 by 578, we get 9 and a remainder of 94.
The next digit of our result is 9. 
Result so far: 1259.0
If we subtract 5202 from 5296, we get 94.
Include the next digit (1) from the dividend after 94, then repeat: 941 / 578

Advancing to step 7:
When dividing 941 by 578, we get 1 with a remainder of 363.
Write down 1 as next digit of the result. 
Result so far: 12591.0
If we subtract 578 from 941, we get 363.
Fetch the next digit (7) from the dividend, attach it to 363 and continue: 3637 / 578

Moving on to step 8:
If we divide 3637 by 578, we get 6 and a remainder of 169.
Write down 6 as next digit of the result. 
Result so far: 125916.0
Deduct 3468 from 3637 and we're left with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Moving on to step 9:
If we divide 1690 by 578, we get 2 and a remainder of 534.
Write down 2 as next digit of the result. 
Result so far: 125916.2
Deduct 1156 from 1690 and we're left with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Moving on to step 10:
578 goes into 5340 9 times with a remainder of 138.
The number 9 becomes the next digit in our result. 
Result so far: 125916.29
If we take 5202 away from 5340, we end up 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 11:
If we divide 1380 by 578, we get 2 and a remainder of 224.
The number 2 becomes the next digit in our result. 
Result so far: 125916.292
Deduct 1156 from 1380 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 12:
578 can be fit into 2240 3 times, resulting in a remainder of 506.
Put 3 as the next digit of the answer. 
Result so far: 125916.2923
If we subtract 1734 from 2240, we get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

On to step 13:
The number 578 fits into 5060 8 times, leaving a remainder of 436.
The next digit of our result is 8. 
Result so far: 125916.29238
Subtract 4624 from 5060 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Advancing to step 14:
578 can be fit into 4360 7 times, resulting in a remainder of 314.
Record the quotient 7 as the next digit in the result. 
Result so far: 125916.292387
If we take 4046 away from 4360, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 15:
578 goes into 3140 5 times with a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 125916.2923875
The remainder is 250 after subtracting 2890 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 16:
578 goes into 2500 4 times with a remainder of 188.
The next digit of our result is 4. 
Result so far: 125916.29238754
The remainder is 188 after subtracting 2312 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

After the division, we end up with 125916.29238754 and a remainder of 1.88e-07.
