Let's divide 6638 by 72
We want to figure out the number of times 6638 can be divided by 72.

Going ahead to step 1:
72 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 72

Step 2:
66 divided by 72 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Append the next digit (3) from the dividend to 66 and continue with: 663 / 72

Let's proceed to step 3:
The number 72 fits into 663 9 times, leaving a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 648 from 663 to get 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 72

Advancing to step 4:
If we divide 158 by 72, we get 2 and a remainder of 14.
The next digit of our result is 2. 
Result so far: 92.0
Deduct 144 from 158 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 5:
The number 72 fits into 140 1 times, leaving a remainder of 68.
The number 1 becomes the next digit in our result. 
Result so far: 92.1
Deduct 72 from 140 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 6:
When dividing 680 by 72, we get 9 with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 92.19
If we take 648 away from 680, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
If we divide 320 by 72, we get 4 and a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 92.194
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
320 divided by 72 is 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 92.1944
Deduct 288 from 320 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 92.1944 and a remainder of 0.00032.
