97102115 ÷ 609 
We're looking to find how many times 609 goes into 97102115.

Let's proceed to step 1:
If we divide 9 by 609, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 609

On to step 2:
97 divided by 609 is 0 with a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Include the next digit (1) from the dividend after 97, then repeat: 971 / 609

Advancing to step 3:
971 divided by 609 is 1 with a remainder of 362.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 609 from 971, we get 362.
Bring next digit (0) of the dividend behind the 362 and repeat the process: 3620 / 609

Step 4:
When dividing 3620 by 609, we get 5 with a remainder of 575.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 3045 from 3620 leaves us with 575.
Include the next digit (2) from the dividend after 575, then repeat: 5752 / 609

Let's proceed to step 5:
If we divide 5752 by 609, we get 9 and a remainder of 271.
Put 9 as the next digit of the answer. 
Result so far: 159.0
The remainder is 271 after subtracting 5481 from 5752.
Take the next digit (1) from the dividend and append it to 271, then repeat: 2711 / 609

Advancing to step 6:
609 can be fit into 2711 4 times, resulting in a remainder of 275.
Record the quotient 4 as the next digit in the result. 
Result so far: 1594.0
Subtract 2436 from 2711 to get 275.
Grab the next digit (1) from the dividend, add it to 275, then carry on: 2751 / 609

Going ahead to step 7:
609 can be fit into 2751 4 times, resulting in a remainder of 315.
Use 4 as the next digit of our solution. 
Result so far: 15944.0
If we subtract 2436 from 2751, we get 315.
Append the next digit (5) from the dividend to 315 and continue with: 3155 / 609

Going ahead to step 8:
If we divide 3155 by 609, we get 5 and a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 159445.0
Deduct 3045 from 3155 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 9:
If we divide 1100 by 609, we get 1 and a remainder of 491.
The number 1 becomes the next digit in our result. 
Result so far: 159445.1
If we take 609 away from 1100, we end up with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Going ahead to step 10:
When dividing 4910 by 609, we get 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 159445.18
If we take 4872 away from 4910, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 11:
609 goes into 380 0 times with a remainder of 380.
The number 0 becomes the next digit in our result. 
Result so far: 159445.18
The remainder is 380 after subtracting 0 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 12:
The number 609 fits into 3800 6 times, leaving a remainder of 146.
Use 6 as the next digit of our solution. 
Result so far: 159445.1806
Subtracting 3654 from 3800 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 13:
If we divide 1460 by 609, we get 2 and a remainder of 242.
Write down 2 as next digit of the result. 
Result so far: 159445.18062
If we take 1218 away from 1460, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 14:
2420 divided by 609 is 3 with a remainder of 593.
The next digit of our result is 3. 
Result so far: 159445.180623
The remainder is 593 after subtracting 1827 from 2420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Advancing to step 15:
If we divide 5930 by 609, we get 9 and a remainder of 449.
Write down 9 as next digit of the result. 
Result so far: 159445.1806239
If we subtract 5481 from 5930, we get 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Going ahead to step 16:
The number 609 fits into 4490 7 times, leaving a remainder of 227.
The number 7 becomes the next digit in our result. 
Result so far: 159445.18062397
Subtracting 4263 from 4490 leaves us with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

After the division, we end up with 159445.18062397 and a remainder of 2.27e-07.
