72644376 divided by 905 
We want to divide 72644376 by 905.

Let's proceed to step 1:
If we divide 7 by 905, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 905

Moving on to step 2:
When dividing 72 by 905, 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.
Include the next digit (6) from the dividend after 72, then repeat: 726 / 905

Going ahead to step 3:
If we divide 726 by 905, we get 0 and a remainder of 726.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 726 to get 726.
Include the next digit (4) from the dividend after 726, then repeat: 7264 / 905

Let's proceed to step 4:
If we divide 7264 by 905, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 7240 from 7264 to get 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 905

Moving on to step 5:
If we divide 244 by 905, we get 0 and a remainder of 244.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Deduct 0 from 244 and we're left with 244.
Append the next digit (3) from the dividend to 244 and continue with: 2443 / 905

Moving on to step 6:
2443 divided by 905 is 2 with a remainder of 633.
Record the quotient 2 as the next digit in the result. 
Result so far: 802.0
Deduct 1810 from 2443 and we're left with 633.
Bring next digit (7) of the dividend behind the 633 and repeat the process: 6337 / 905

On to step 7:
If we divide 6337 by 905, we get 7 and a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 8027.0
If we take 6335 away from 6337, we end up with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 905

Step 8:
905 can be fit into 26 0 times, resulting in a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 80270.0
If we subtract 0 from 26, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
905 can be fit into 260 0 times, resulting in a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 80270.0
The remainder is 260 after subtracting 0 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 10:
905 can be fit into 2600 2 times, resulting in a remainder of 790.
Use 2 as the next digit of our solution. 
Result so far: 80270.02
Deduct 1810 from 2600 and we're left with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Advancing to step 11:
905 goes into 7900 8 times with a remainder of 660.
Write down 8 as next digit of the result. 
Result so far: 80270.028
The remainder is 660 after subtracting 7240 from 7900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Step 12:
905 can be fit into 6600 7 times, resulting in a remainder of 265.
Write down 7 as next digit of the result. 
Result so far: 80270.0287
Subtracting 6335 from 6600 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 13:
When dividing 2650 by 905, we get 2 with a remainder of 840.
Put 2 as the next digit of the answer. 
Result so far: 80270.02872
Deduct 1810 from 2650 and we're left with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

On to step 14:
905 goes into 8400 9 times with a remainder of 255.
Put 9 as the next digit of the answer. 
Result so far: 80270.028729
If we take 8145 away from 8400, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Moving on to step 15:
The number 905 fits into 2550 2 times, leaving a remainder of 740.
Write down 2 as next digit of the result. 
Result so far: 80270.0287292
If we take 1810 away from 2550, we end up with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

On to step 16:
7400 divided by 905 is 8 with a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 80270.02872928
Subtract 7240 from 7400 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

After the division, we end up with 80270.02872928 and a remainder of 1.6e-07.
