We're dividing 97815803 by 159 
We want to figure out the number of times 97815803 can be divided by 159.

Let's proceed to step 1:
159 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 159

Going ahead to step 2:
159 goes into 97 0 times with a remainder of 97.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Append the next digit (8) from the dividend to 97 and continue with: 978 / 159

Going ahead to step 3:
When dividing 978 by 159, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 954 away from 978, we end up with 24.
Take the next digit (1) from the dividend and append it to 24, then repeat: 241 / 159

Step 4:
159 can be fit into 241 1 times, resulting in a remainder of 82.
Use 1 as the next digit of our solution. 
Result so far: 61.0
If we take 159 away from 241, we end up with 82.
Take the next digit (5) from the dividend and append it to 82, then repeat: 825 / 159

On to step 5:
159 goes into 825 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 615.0
Deduct 795 from 825 and we're left with 30.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 159

Going ahead to step 6:
159 can be fit into 308 1 times, resulting in a remainder of 149.
The number 1 becomes the next digit in our result. 
Result so far: 6151.0
Deduct 159 from 308 and we're left with 149.
Append the next digit (0) from the dividend to 149 and continue with: 1490 / 159

On to step 7:
159 goes into 1490 9 times with a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 61519.0
If we take 1431 away from 1490, we end up with 59.
Append the next digit (3) from the dividend to 59 and continue with: 593 / 159

Moving on to step 8:
159 goes into 593 3 times with a remainder of 116.
Use 3 as the next digit of our solution. 
Result so far: 615193.0
Subtract 477 from 593 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 9:
If we divide 1160 by 159, we get 7 and a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 615193.7
Deduct 1113 from 1160 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.

On to step 10:
The number 159 fits into 470 2 times, leaving a remainder of 152.
The number 2 becomes the next digit in our result. 
Result so far: 615193.72
Deduct 318 from 470 and we're left 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.

On to step 11:
1520 divided by 159 is 9 with a remainder of 89.
The number 9 becomes the next digit in our result. 
Result so far: 615193.729
The remainder is 89 after subtracting 1431 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 12:
159 goes into 890 5 times with a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 615193.7295
If we take 795 away from 890, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 13:
950 divided by 159 is 5 with a remainder of 155.
The next digit of our result is 5. 
Result so far: 615193.72955
If we take 795 away from 950, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

In conclusion, the division gives 615193.72955 with a balance of 0.000155.
