72166156 ÷ 97 
Our goal is to divide 72166156 by 97.

Step 1:
97 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 97

On to step 2:
97 goes into 72 0 times with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Fetch the next digit (1) from the dividend, attach it to 72 and continue: 721 / 97

Moving on to step 3:
The number 97 fits into 721 7 times, leaving a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 679 away from 721, we end up with 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 97

Step 4:
97 can be fit into 426 4 times, resulting in a remainder of 38.
The next digit of our result is 4. 
Result so far: 74.0
If we take 388 away from 426, we end up with 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 97

On to step 5:
386 divided by 97 is 3 with a remainder of 95.
The next digit of our result is 3. 
Result so far: 743.0
Subtract 291 from 386 to get 95.
Bring next digit (1) of the dividend behind the 95 and repeat the process: 951 / 97

Going ahead to step 6:
If we divide 951 by 97, we get 9 and a remainder of 78.
The next digit of our result is 9. 
Result so far: 7439.0
If we subtract 873 from 951, we get 78.
Take the next digit (5) from the dividend and append it to 78, then repeat: 785 / 97

Going ahead to step 7:
The number 97 fits into 785 8 times, leaving a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 74398.0
Deduct 776 from 785 and we're left with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 97

Advancing to step 8:
97 can be fit into 96 0 times, resulting in a remainder of 96.
Write down 0 as next digit of the result. 
Result so far: 743980.0
If we subtract 0 from 96, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 9:
The number 97 fits into 960 9 times, leaving a remainder of 87.
Record the quotient 9 as the next digit in the result. 
Result so far: 743980.9
Deduct 873 from 960 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 10:
97 goes into 870 8 times with a remainder of 94.
The number 8 becomes the next digit in our result. 
Result so far: 743980.98
Subtracting 776 from 870 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 11:
97 goes into 940 9 times with a remainder of 67.
Use 9 as the next digit of our solution. 
Result so far: 743980.989
Subtract 873 from 940 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 12:
The number 97 fits into 670 6 times, leaving a remainder of 88.
Record the quotient 6 as the next digit in the result. 
Result so far: 743980.9896
If we subtract 582 from 670, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 13:
If we divide 880 by 97, we get 9 and a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 743980.98969
Deduct 873 from 880 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 14:
97 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 743980.98969
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 15:
The number 97 fits into 700 7 times, leaving a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 743980.9896907
Subtracting 679 from 700 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 16:
210 divided by 97 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 743980.98969072
Subtracting 194 from 210 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 743980.98969072, and the remainder is 1.6e-08.
