Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 97

Step 2:
The number 97 fits into 72 0 times, leaving a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Fetch the next digit (0) from the dividend, attach it to 72 and continue: 720 / 97

On to step 3:
If we divide 720 by 97, we get 7 and a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 679 from 720 to get 41.
Take the next digit (0) from the dividend and append it to 41, then repeat: 410 / 97

Advancing to step 4:
410 divided by 97 is 4 with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
If we subtract 388 from 410, we get 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 97

Step 5:
225 divided by 97 is 2 with a remainder of 31.
The number 2 becomes the next digit in our result. 
Result so far: 742.0
Deduct 194 from 225 and we're left with 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 97

Moving on to step 6:
97 can be fit into 315 3 times, resulting in a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 7423.0
Deduct 291 from 315 and we're left with 24.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 97

Advancing to step 7:
When dividing 248 by 97, we get 2 with a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 74232.0
Subtracting 194 from 248 leaves us with 54.
Fetch the next digit (8) from the dividend, attach it to 54 and continue: 548 / 97

On to step 8:
If we divide 548 by 97, we get 5 and a remainder of 63.
Record the quotient 5 as the next digit in the result. 
Result so far: 742325.0
Deduct 485 from 548 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 9:
97 goes into 630 6 times with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 742325.6
Subtract 582 from 630 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
When dividing 480 by 97, we get 4 with a remainder of 92.
Write down 4 as next digit of the result. 
Result so far: 742325.64
If we take 388 away from 480, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 11:
If we divide 920 by 97, we get 9 and a remainder of 47.
The next digit of our result is 9. 
Result so far: 742325.649
Deduct 873 from 920 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 12:
If we divide 470 by 97, we get 4 and a remainder of 82.
Use 4 as the next digit of our solution. 
Result so far: 742325.6494
The remainder is 82 after subtracting 388 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 13:
If we divide 820 by 97, we get 8 and a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 742325.64948
The remainder is 44 after subtracting 776 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 14:
If we divide 440 by 97, we get 4 and a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 742325.649484
Subtract 388 from 440 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 15:
97 goes into 520 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 742325.6494845
Subtracting 485 from 520 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 16:
97 goes into 350 3 times with a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 742325.64948453
If we subtract 291 from 350, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

After the division, we end up with 742325.64948453 and a remainder of 5.9e-08.
