81438081 ÷ 972 
We're looking to find how many times 972 goes into 81438081.

Going ahead to step 1:
The number 972 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 972

Going ahead to step 2:
The number 972 fits into 81 0 times, leaving a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Fetch the next digit (4) from the dividend, attach it to 81 and continue: 814 / 972

On to step 3:
If we divide 814 by 972, we get 0 and a remainder of 814.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 814, we end up with 814.
Append the next digit (3) from the dividend to 814 and continue with: 8143 / 972

On to step 4:
972 goes into 8143 8 times with a remainder of 367.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 7776 from 8143 to get 367.
Fetch the next digit (8) from the dividend, attach it to 367 and continue: 3678 / 972

Moving on to step 5:
When dividing 3678 by 972, we get 3 with a remainder of 762.
Write down 3 as next digit of the result. 
Result so far: 83.0
Deduct 2916 from 3678 and we're left with 762.
Bring next digit (0) of the dividend behind the 762 and repeat the process: 7620 / 972

Step 6:
The number 972 fits into 7620 7 times, leaving a remainder of 816.
Use 7 as the next digit of our solution. 
Result so far: 837.0
The remainder is 816 after subtracting 6804 from 7620.
Grab the next digit (8) from the dividend, add it to 816, then carry on: 8168 / 972

Moving on to step 7:
If we divide 8168 by 972, we get 8 and a remainder of 392.
Put 8 as the next digit of the answer. 
Result so far: 8378.0
The remainder is 392 after subtracting 7776 from 8168.
Include the next digit (1) from the dividend after 392, then repeat: 3921 / 972

Step 8:
If we divide 3921 by 972, we get 4 and a remainder of 33.
Put 4 as the next digit of the answer. 
Result so far: 83784.0
If we take 3888 away from 3921, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 9:
When dividing 330 by 972, we get 0 with a remainder of 330.
Use 0 as the next digit of our solution. 
Result so far: 83784.0
Subtract 0 from 330 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 10:
3300 divided by 972 is 3 with a remainder of 384.
Use 3 as the next digit of our solution. 
Result so far: 83784.03
If we subtract 2916 from 3300, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 11:
If we divide 3840 by 972, we get 3 and a remainder of 924.
The number 3 becomes the next digit in our result. 
Result so far: 83784.033
Deduct 2916 from 3840 and we're left with 924.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9240, and continue the process.

The final outcome is 83784.033, with a leftover of 0.0924.
