97189009 ÷ 715 
We want to divide 97189009 by 715.

Let's proceed to step 1:
715 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 715

Going ahead to step 2:
When dividing 97 by 715, we get 0 with a remainder of 97.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Append the next digit (1) from the dividend to 97 and continue with: 971 / 715

Advancing to step 3:
The number 715 fits into 971 1 times, leaving a remainder of 256.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 715 from 971, we get 256.
Include the next digit (8) from the dividend after 256, then repeat: 2568 / 715

Moving on to step 4:
If we divide 2568 by 715, we get 3 and a remainder of 423.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 423 after subtracting 2145 from 2568.
Grab the next digit (9) from the dividend, add it to 423, then carry on: 4239 / 715

Let's proceed to step 5:
4239 divided by 715 is 5 with a remainder of 664.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
If we take 3575 away from 4239, we end up with 664.
Include the next digit (0) from the dividend after 664, then repeat: 6640 / 715

Step 6:
715 can be fit into 6640 9 times, resulting in a remainder of 205.
Write down 9 as next digit of the result. 
Result so far: 1359.0
Subtracting 6435 from 6640 leaves us with 205.
Append the next digit (0) from the dividend to 205 and continue with: 2050 / 715

Step 7:
If we divide 2050 by 715, we get 2 and a remainder of 620.
Write down 2 as next digit of the result. 
Result so far: 13592.0
If we take 1430 away from 2050, we end up with 620.
Include the next digit (9) from the dividend after 620, then repeat: 6209 / 715

Going ahead to step 8:
If we divide 6209 by 715, we get 8 and a remainder of 489.
The number 8 becomes the next digit in our result. 
Result so far: 135928.0
Deduct 5720 from 6209 and we're left with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Moving on to step 9:
If we divide 4890 by 715, we get 6 and a remainder of 600.
The number 6 becomes the next digit in our result. 
Result so far: 135928.6
Subtracting 4290 from 4890 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 10:
6000 divided by 715 is 8 with a remainder of 280.
Record the quotient 8 as the next digit in the result. 
Result so far: 135928.68
If we subtract 5720 from 6000, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 11:
If we divide 2800 by 715, we get 3 and a remainder of 655.
Record the quotient 3 as the next digit in the result. 
Result so far: 135928.683
Deduct 2145 from 2800 and we're left with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Step 12:
The number 715 fits into 6550 9 times, leaving a remainder of 115.
Use 9 as the next digit of our solution. 
Result so far: 135928.6839
Subtracting 6435 from 6550 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 13:
If we divide 1150 by 715, we get 1 and a remainder of 435.
Put 1 as the next digit of the answer. 
Result so far: 135928.68391
If we take 715 away from 1150, we end up with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Step 14:
The number 715 fits into 4350 6 times, leaving a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 135928.683916
Subtract 4290 from 4350 to 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.

Advancing to step 15:
If we divide 600 by 715, we get 0 and a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 135928.683916
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 16:
715 goes into 6000 8 times with a remainder of 280.
The number 8 becomes the next digit in our result. 
Result so far: 135928.68391608
The remainder is 280 after subtracting 5720 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 135928.68391608, with a leftover of 2.8e-07.
