We look at the division of 97761624 by 172 
Our goal is to divide 97761624 by 172.

Step 1:
The number 172 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 172

Going ahead to step 2:
172 can be fit into 97 0 times, resulting in a remainder of 97.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 97 to get 97.
Append the next digit (7) from the dividend to 97 and continue with: 977 / 172

Moving on to step 3:
If we divide 977 by 172, we get 5 and a remainder of 117.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 860 from 977 to get 117.
Grab the next digit (6) from the dividend, add it to 117, then carry on: 1176 / 172

Going ahead to step 4:
1176 divided by 172 is 6 with a remainder of 144.
Write down 6 as next digit of the result. 
Result so far: 56.0
Subtracting 1032 from 1176 leaves us with 144.
Append the next digit (1) from the dividend to 144 and continue with: 1441 / 172

Step 5:
When dividing 1441 by 172, we get 8 with a remainder of 65.
Record the quotient 8 as the next digit in the result. 
Result so far: 568.0
The remainder is 65 after subtracting 1376 from 1441.
Grab the next digit (6) from the dividend, add it to 65, then carry on: 656 / 172

Let's proceed to step 6:
656 divided by 172 is 3 with a remainder of 140.
Use 3 as the next digit of our solution. 
Result so far: 5683.0
If we subtract 516 from 656, we get 140.
Include the next digit (2) from the dividend after 140, then repeat: 1402 / 172

Moving on to step 7:
When dividing 1402 by 172, we get 8 with a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 56838.0
Deduct 1376 from 1402 and we're left with 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 172

On to step 8:
172 goes into 264 1 times with a remainder of 92.
The number 1 becomes the next digit in our result. 
Result so far: 568381.0
If we take 172 away from 264, 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 9:
920 divided by 172 is 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 568381.5
If we subtract 860 from 920, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
172 goes into 600 3 times with a remainder of 84.
Put 3 as the next digit of the answer. 
Result so far: 568381.53
If we take 516 away from 600, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 11:
172 can be fit into 840 4 times, resulting in a remainder of 152.
Record the quotient 4 as the next digit in the result. 
Result so far: 568381.534
Subtracting 688 from 840 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 12:
The number 172 fits into 1520 8 times, leaving a remainder of 144.
The number 8 becomes the next digit in our result. 
Result so far: 568381.5348
Subtract 1376 from 1520 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 13:
172 goes into 1440 8 times with a remainder of 64.
The next digit of our result is 8. 
Result so far: 568381.53488
Subtracting 1376 from 1440 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 568381.53488, with a leftover of 6.4e-05.
