72160040 divided by 891 
Our goal is to divide 72160040 by 891.

Advancing to step 1:
891 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 891

Let's proceed to step 2:
The number 891 fits into 72 0 times, leaving a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 891

Moving on to step 3:
If we divide 721 by 891, we get 0 and a remainder of 721.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 721 to get 721.
Append the next digit (6) from the dividend to 721 and continue with: 7216 / 891

Advancing to step 4:
7216 divided by 891 is 8 with a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 7128 from 7216, we get 88.
Include the next digit (0) from the dividend after 88, then repeat: 880 / 891

On to step 5:
The number 891 fits into 880 0 times, leaving a remainder of 880.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtracting 0 from 880 leaves us with 880.
Grab the next digit (0) from the dividend, add it to 880, then carry on: 8800 / 891

Step 6:
891 goes into 8800 9 times with a remainder of 781.
Write down 9 as next digit of the result. 
Result so far: 809.0
If we subtract 8019 from 8800, we get 781.
Take the next digit (4) from the dividend and append it to 781, then repeat: 7814 / 891

Let's proceed to step 7:
If we divide 7814 by 891, we get 8 and a remainder of 686.
Record the quotient 8 as the next digit in the result. 
Result so far: 8098.0
Deduct 7128 from 7814 and we're left with 686.
Grab the next digit (0) from the dividend, add it to 686, then carry on: 6860 / 891

Step 8:
When dividing 6860 by 891, we get 7 with a remainder of 623.
Record the quotient 7 as the next digit in the result. 
Result so far: 80987.0
Deduct 6237 from 6860 and we're left with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Moving on to step 9:
6230 divided by 891 is 6 with a remainder of 884.
Record the quotient 6 as the next digit in the result. 
Result so far: 80987.6
Deduct 5346 from 6230 and we're left with 884.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8840, and continue the process.

Step 10:
891 goes into 8840 9 times with a remainder of 821.
Write down 9 as next digit of the result. 
Result so far: 80987.69
The remainder is 821 after subtracting 8019 from 8840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8210, and continue the process.

Let's proceed to step 11:
8210 divided by 891 is 9 with a remainder of 191.
Write down 9 as next digit of the result. 
Result so far: 80987.699
The remainder is 191 after subtracting 8019 from 8210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Our division results in 80987.699 with a remaining 0.0191.
