686164 divided by 72 
Our goal is to divide 686164 by 72.

Moving on to step 1:
When dividing 6 by 72, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 72

Let's proceed to step 2:
68 divided by 72 is 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Grab the next digit (6) from the dividend, add it to 68, then carry on: 686 / 72

Going ahead to step 3:
The number 72 fits into 686 9 times, leaving a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 648 from 686 leaves us with 38.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 72

Going ahead to step 4:
If we divide 381 by 72, we get 5 and a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
If we take 360 away from 381, we end up with 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 72

Step 5:
216 divided by 72 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 953.0
Deduct 216 from 216 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 72

On to step 6:
When dividing 4 by 72, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 9530.0
If we subtract 0 from 4, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
40 divided by 72 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 9530.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
72 goes into 400 5 times with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 9530.05
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
400 divided by 72 is 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 9530.055
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 9530.055, and the remainder is 0.004.
