68639215 ÷ 973 
We want to divide 68639215 by 973.

Step 1:
If we divide 6 by 973, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 973

Let's proceed to step 2:
The number 973 fits into 68 0 times, leaving a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 973

Advancing to step 3:
973 can be fit into 686 0 times, resulting in a remainder of 686.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 686 after subtracting 0 from 686.
Bring next digit (3) of the dividend behind the 686 and repeat the process: 6863 / 973

On to step 4:
6863 divided by 973 is 7 with a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 6811 from 6863 to get 52.
Fetch the next digit (9) from the dividend, attach it to 52 and continue: 529 / 973

Advancing to step 5:
The number 973 fits into 529 0 times, leaving a remainder of 529.
The next digit of our result is 0. 
Result so far: 70.0
If we take 0 away from 529, we end up with 529.
Fetch the next digit (2) from the dividend, attach it to 529 and continue: 5292 / 973

Advancing to step 6:
973 goes into 5292 5 times with a remainder of 427.
Record the quotient 5 as the next digit in the result. 
Result so far: 705.0
Subtracting 4865 from 5292 leaves us with 427.
Fetch the next digit (1) from the dividend, attach it to 427 and continue: 4271 / 973

Going ahead to step 7:
If we divide 4271 by 973, we get 4 and a remainder of 379.
The number 4 becomes the next digit in our result. 
Result so far: 7054.0
If we subtract 3892 from 4271, we get 379.
Fetch the next digit (5) from the dividend, attach it to 379 and continue: 3795 / 973

Going ahead to step 8:
If we divide 3795 by 973, we get 3 and a remainder of 876.
Record the quotient 3 as the next digit in the result. 
Result so far: 70543.0
If we subtract 2919 from 3795, we get 876.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8760, and continue the process.

Advancing to step 9:
If we divide 8760 by 973, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 70543.9
Subtracting 8757 from 8760 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
973 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 70543.9
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
If we divide 300 by 973, we get 0 and a remainder of 300.
The next digit of our result is 0. 
Result so far: 70543.9
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The quotient of the division is 70543.9, and the remainder is 0.03.
