We look at the division of 561891 by 72 
Let's see how many times 72 fits into 561891.

Going ahead to step 1:
5 divided by 72 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 72

Advancing to step 2:
72 can be fit into 56 0 times, resulting in a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Append the next digit (1) from the dividend to 56 and continue with: 561 / 72

Let's proceed to step 3:
When dividing 561 by 72, we get 7 with a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 504 away from 561, we end up with 57.
Include the next digit (8) from the dividend after 57, then repeat: 578 / 72

Going ahead to step 4:
72 goes into 578 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Deduct 576 from 578 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 72

Advancing to step 5:
72 can be fit into 29 0 times, resulting in a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 780.0
If we subtract 0 from 29, we get 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 72

Let's proceed to step 6:
72 goes into 291 4 times with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 7804.0
If we subtract 288 from 291, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
If we divide 30 by 72, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 7804.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
The number 72 fits into 300 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 7804.04
Subtract 288 from 300 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
If we divide 120 by 72, we get 1 and a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 7804.041
Subtract 72 from 120 to 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.

Moving on to step 10:
When dividing 480 by 72, we get 6 with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 7804.0416
Subtract 432 from 480 to 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.

Going ahead to step 11:
If we divide 480 by 72, we get 6 and a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 7804.04166
Subtract 432 from 480 to 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.

After the division, we end up with 7804.04166 and a remainder of 4.8e-05.
