97367117 ÷ 645 
We want to divide 97367117 by 645.

On to step 1:
When dividing 9 by 645, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 645

On to step 2:
The number 645 fits into 97 0 times, leaving a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Bring next digit (3) of the dividend behind the 97 and repeat the process: 973 / 645

Going ahead to step 3:
973 divided by 645 is 1 with a remainder of 328.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 645 from 973 and we're left with 328.
Fetch the next digit (6) from the dividend, attach it to 328 and continue: 3286 / 645

Advancing to step 4:
When dividing 3286 by 645, we get 5 with a remainder of 61.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 3225 from 3286 leaves us with 61.
Include the next digit (7) from the dividend after 61, then repeat: 617 / 645

Going ahead to step 5:
The number 645 fits into 617 0 times, leaving a remainder of 617.
Put 0 as the next digit of the answer. 
Result so far: 150.0
If we take 0 away from 617, we end up with 617.
Take the next digit (1) from the dividend and append it to 617, then repeat: 6171 / 645

Step 6:
If we divide 6171 by 645, we get 9 and a remainder of 366.
Record the quotient 9 as the next digit in the result. 
Result so far: 1509.0
If we subtract 5805 from 6171, we get 366.
Fetch the next digit (1) from the dividend, attach it to 366 and continue: 3661 / 645

Advancing to step 7:
645 can be fit into 3661 5 times, resulting in a remainder of 436.
The next digit of our result is 5. 
Result so far: 15095.0
If we subtract 3225 from 3661, we get 436.
Bring next digit (7) of the dividend behind the 436 and repeat the process: 4367 / 645

Let's proceed to step 8:
645 goes into 4367 6 times with a remainder of 497.
Use 6 as the next digit of our solution. 
Result so far: 150956.0
If we take 3870 away from 4367, we end up with 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Step 9:
The number 645 fits into 4970 7 times, leaving a remainder of 455.
Write down 7 as next digit of the result. 
Result so far: 150956.7
Deduct 4515 from 4970 and we're left with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Let's proceed to step 10:
The number 645 fits into 4550 7 times, leaving a remainder of 35.
The next digit of our result is 7. 
Result so far: 150956.77
Deduct 4515 from 4550 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 150956.77 with a remainder of 0.035.
