We're dividing 77551771 by 973 
We're looking to find how many times 973 goes into 77551771.

Step 1:
The number 973 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 973

Step 2:
77 divided by 973 is 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Fetch the next digit (5) from the dividend, attach it to 77 and continue: 775 / 973

On to step 3:
973 goes into 775 0 times with a remainder of 775.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 775, we end up with 775.
Append the next digit (5) from the dividend to 775 and continue with: 7755 / 973

Let's proceed to step 4:
The number 973 fits into 7755 7 times, leaving a remainder of 944.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 6811 from 7755 to get 944.
Grab the next digit (1) from the dividend, add it to 944, then carry on: 9441 / 973

Step 5:
The number 973 fits into 9441 9 times, leaving a remainder of 684.
The next digit of our result is 9. 
Result so far: 79.0
Subtracting 8757 from 9441 leaves us with 684.
Take the next digit (7) from the dividend and append it to 684, then repeat: 6847 / 973

On to step 6:
When dividing 6847 by 973, we get 7 with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 797.0
The remainder is 36 after subtracting 6811 from 6847.
Bring next digit (7) of the dividend behind the 36 and repeat the process: 367 / 973

On to step 7:
973 can be fit into 367 0 times, resulting in a remainder of 367.
Use 0 as the next digit of our solution. 
Result so far: 7970.0
Subtracting 0 from 367 leaves us with 367.
Fetch the next digit (1) from the dividend, attach it to 367 and continue: 3671 / 973

Let's proceed to step 8:
The number 973 fits into 3671 3 times, leaving a remainder of 752.
Record the quotient 3 as the next digit in the result. 
Result so far: 79703.0
Subtracting 2919 from 3671 leaves us with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Let's proceed to step 9:
973 goes into 7520 7 times with a remainder of 709.
Use 7 as the next digit of our solution. 
Result so far: 79703.7
Subtract 6811 from 7520 to get 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Step 10:
When dividing 7090 by 973, we get 7 with a remainder of 279.
Put 7 as the next digit of the answer. 
Result so far: 79703.77
Subtract 6811 from 7090 to get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

After the division, we end up with 79703.77 and a remainder of 0.279.
