We divide 869888 by 72
Our goal is to divide 869888 by 72.

Moving on to step 1:
The number 72 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 72

Advancing to step 2:
86 divided by 72 is 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 72 away from 86, we end up with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 72

Moving on to step 3:
72 goes into 149 2 times with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 144 from 149 to get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 72

Going ahead to step 4:
72 goes into 58 0 times with a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
If we take 0 away from 58, we end up with 58.
Bring next digit (8) of the dividend behind the 58 and repeat the process: 588 / 72

Advancing to step 5:
The number 72 fits into 588 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 1208.0
If we subtract 576 from 588, we get 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 72

Let's proceed to step 6:
72 goes into 128 1 times with a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 12081.0
Deduct 72 from 128 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 7:
When dividing 560 by 72, we get 7 with a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 12081.7
Deduct 504 from 560 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 8:
If we divide 560 by 72, we get 7 and a remainder of 56.
Use 7 as the next digit of our solution. 
Result so far: 12081.77
The remainder is 56 after subtracting 504 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 12081.77 and a remainder of 0.056.
