96797057 ÷ 645 
Our goal is to divide 96797057 by 645.

Step 1:
If we divide 9 by 645, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 645

Moving on to step 2:
96 divided by 645 is 0 with a remainder of 96.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 96, we end up with 96.
Append the next digit (7) from the dividend to 96 and continue with: 967 / 645

Let's proceed to step 3:
645 goes into 967 1 times with a remainder of 322.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 645 from 967 leaves us with 322.
Include the next digit (9) from the dividend after 322, then repeat: 3229 / 645

Moving on to step 4:
645 can be fit into 3229 5 times, resulting in a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 3225 away from 3229, we end up with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 645

Going ahead to step 5:
If we divide 47 by 645, we get 0 and a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 150.0
Subtract 0 from 47 to get 47.
Take the next digit (0) from the dividend and append it to 47, then repeat: 470 / 645

Let's proceed to step 6:
470 divided by 645 is 0 with a remainder of 470.
Record the quotient 0 as the next digit in the result. 
Result so far: 1500.0
Deduct 0 from 470 and we're left with 470.
Fetch the next digit (5) from the dividend, attach it to 470 and continue: 4705 / 645

On to step 7:
The number 645 fits into 4705 7 times, leaving a remainder of 190.
Write down 7 as next digit of the result. 
Result so far: 15007.0
Subtract 4515 from 4705 to get 190.
Append the next digit (7) from the dividend to 190 and continue with: 1907 / 645

Moving on to step 8:
If we divide 1907 by 645, we get 2 and a remainder of 617.
Use 2 as the next digit of our solution. 
Result so far: 150072.0
The remainder is 617 after subtracting 1290 from 1907.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Going ahead to step 9:
When dividing 6170 by 645, we get 9 with a remainder of 365.
The number 9 becomes the next digit in our result. 
Result so far: 150072.9
Subtract 5805 from 6170 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

On to step 10:
If we divide 3650 by 645, we get 5 and a remainder of 425.
Put 5 as the next digit of the answer. 
Result so far: 150072.95
Deduct 3225 from 3650 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Let's proceed to step 11:
4250 divided by 645 is 6 with a remainder of 380.
The next digit of our result is 6. 
Result so far: 150072.956
The remainder is 380 after subtracting 3870 from 4250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 12:
If we divide 3800 by 645, we get 5 and a remainder of 575.
Put 5 as the next digit of the answer. 
Result so far: 150072.9565
Subtracting 3225 from 3800 leaves us with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Going ahead to step 13:
The number 645 fits into 5750 8 times, leaving a remainder of 590.
The number 8 becomes the next digit in our result. 
Result so far: 150072.95658
Subtract 5160 from 5750 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 14:
The number 645 fits into 5900 9 times, leaving a remainder of 95.
Use 9 as the next digit of our solution. 
Result so far: 150072.956589
If we take 5805 away from 5900, 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 15:
645 can be fit into 950 1 times, resulting in a remainder of 305.
Record the quotient 1 as the next digit in the result. 
Result so far: 150072.9565891
If we take 645 away from 950, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 16:
645 goes into 3050 4 times with a remainder of 470.
Record the quotient 4 as the next digit in the result. 
Result so far: 150072.95658914
The remainder is 470 after subtracting 2580 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

The final result is 150072.95658914 with a remainder of 4.7e-07.
