We're dividing 73021221 by 777 
We're looking to find how many times 777 goes into 73021221.

Going ahead to step 1:
777 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 777

On to step 2:
The number 777 fits into 73 0 times, leaving a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Append the next digit (0) from the dividend to 73 and continue with: 730 / 777

On to step 3:
730 divided by 777 is 0 with a remainder of 730.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 730 after subtracting 0 from 730.
Grab the next digit (2) from the dividend, add it to 730, then carry on: 7302 / 777

Step 4:
7302 divided by 777 is 9 with a remainder of 309.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 6993 from 7302 and we're left with 309.
Take the next digit (1) from the dividend and append it to 309, then repeat: 3091 / 777

Advancing to step 5:
When dividing 3091 by 777, we get 3 with a remainder of 760.
The next digit of our result is 3. 
Result so far: 93.0
If we take 2331 away from 3091, we end up with 760.
Fetch the next digit (2) from the dividend, attach it to 760 and continue: 7602 / 777

Moving on to step 6:
The number 777 fits into 7602 9 times, leaving a remainder of 609.
Put 9 as the next digit of the answer. 
Result so far: 939.0
Subtracting 6993 from 7602 leaves us with 609.
Fetch the next digit (2) from the dividend, attach it to 609 and continue: 6092 / 777

Step 7:
If we divide 6092 by 777, we get 7 and a remainder of 653.
Put 7 as the next digit of the answer. 
Result so far: 9397.0
Deduct 5439 from 6092 and we're left with 653.
Grab the next digit (1) from the dividend, add it to 653, then carry on: 6531 / 777

Let's proceed to step 8:
When dividing 6531 by 777, we get 8 with a remainder of 315.
The next digit of our result is 8. 
Result so far: 93978.0
If we take 6216 away from 6531, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 9:
777 can be fit into 3150 4 times, resulting in a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 93978.4
The remainder is 42 after subtracting 3108 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
777 can be fit into 420 0 times, resulting in a remainder of 420.
The number 0 becomes the next digit in our result. 
Result so far: 93978.4
If we take 0 away from 420, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 11:
777 can be fit into 4200 5 times, resulting in a remainder of 315.
The next digit of our result is 5. 
Result so far: 93978.405
Subtract 3885 from 4200 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Let's proceed to step 12:
The number 777 fits into 3150 4 times, leaving a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 93978.4054
Deduct 3108 from 3150 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
777 can be fit into 420 0 times, resulting in a remainder of 420.
The next digit of our result is 0. 
Result so far: 93978.4054
If we take 0 away from 420, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 14:
4200 divided by 777 is 5 with a remainder of 315.
Use 5 as the next digit of our solution. 
Result so far: 93978.405405
Subtracting 3885 from 4200 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 15:
777 goes into 3150 4 times with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 93978.4054054
The remainder is 42 after subtracting 3108 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 16:
777 can be fit into 420 0 times, resulting in a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 93978.4054054
The remainder is 420 after subtracting 0 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

The final outcome is 93978.4054054, with a leftover of 4.2e-07.
