97419771 ÷ 578 
We want to divide 97419771 by 578.

Step 1:
If we divide 9 by 578, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 578

Moving on to step 2:
578 goes into 97 0 times with a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Grab the next digit (4) from the dividend, add it to 97, then carry on: 974 / 578

On to step 3:
If we divide 974 by 578, we get 1 and a remainder of 396.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 578 from 974 to get 396.
Include the next digit (1) from the dividend after 396, then repeat: 3961 / 578

Let's proceed to step 4:
578 can be fit into 3961 6 times, resulting in a remainder of 493.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 493 after subtracting 3468 from 3961.
Fetch the next digit (9) from the dividend, attach it to 493 and continue: 4939 / 578

Step 5:
When dividing 4939 by 578, we get 8 with a remainder of 315.
The next digit of our result is 8. 
Result so far: 168.0
Subtract 4624 from 4939 to get 315.
Bring next digit (7) of the dividend behind the 315 and repeat the process: 3157 / 578

Going ahead to step 6:
The number 578 fits into 3157 5 times, leaving a remainder of 267.
Put 5 as the next digit of the answer. 
Result so far: 1685.0
Subtracting 2890 from 3157 leaves us with 267.
Fetch the next digit (7) from the dividend, attach it to 267 and continue: 2677 / 578

Going ahead to step 7:
578 can be fit into 2677 4 times, resulting in a remainder of 365.
Record the quotient 4 as the next digit in the result. 
Result so far: 16854.0
If we subtract 2312 from 2677, we get 365.
Append the next digit (1) from the dividend to 365 and continue with: 3651 / 578

Advancing to step 8:
578 goes into 3651 6 times with a remainder of 183.
Write down 6 as next digit of the result. 
Result so far: 168546.0
Deduct 3468 from 3651 and we're left with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 9:
When dividing 1830 by 578, we get 3 with a remainder of 96.
Use 3 as the next digit of our solution. 
Result so far: 168546.3
Subtract 1734 from 1830 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 10:
If we divide 960 by 578, we get 1 and a remainder of 382.
Write down 1 as next digit of the result. 
Result so far: 168546.31
If we take 578 away from 960, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Moving on to step 11:
When dividing 3820 by 578, we get 6 with a remainder of 352.
Put 6 as the next digit of the answer. 
Result so far: 168546.316
Deduct 3468 from 3820 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 12:
The number 578 fits into 3520 6 times, leaving a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 168546.3166
Deduct 3468 from 3520 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 168546.3166 with a remainder of 0.00052.
