We look at the division of 76721212 by 477 
We're looking to find how many times 477 goes into 76721212.

Step 1:
The number 477 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 477

Moving on to step 2:
When dividing 76 by 477, we get 0 with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Bring next digit (7) of the dividend behind the 76 and repeat the process: 767 / 477

Step 3:
When dividing 767 by 477, we get 1 with a remainder of 290.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 290 after subtracting 477 from 767.
Fetch the next digit (2) from the dividend, attach it to 290 and continue: 2902 / 477

Advancing to step 4:
477 goes into 2902 6 times with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 2862 from 2902 and we're left with 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 477

Let's proceed to step 5:
When dividing 401 by 477, we get 0 with a remainder of 401.
Use 0 as the next digit of our solution. 
Result so far: 160.0
If we take 0 away from 401, we end up with 401.
Include the next digit (2) from the dividend after 401, then repeat: 4012 / 477

Step 6:
477 can be fit into 4012 8 times, resulting in a remainder of 196.
Write down 8 as next digit of the result. 
Result so far: 1608.0
The remainder is 196 after subtracting 3816 from 4012.
Include the next digit (1) from the dividend after 196, then repeat: 1961 / 477

On to step 7:
If we divide 1961 by 477, we get 4 and a remainder of 53.
Record the quotient 4 as the next digit in the result. 
Result so far: 16084.0
Deduct 1908 from 1961 and we're left with 53.
Fetch the next digit (2) from the dividend, attach it to 53 and continue: 532 / 477

On to step 8:
477 can be fit into 532 1 times, resulting in a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 160841.0
If we subtract 477 from 532, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 9:
The number 477 fits into 550 1 times, leaving a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 160841.1
Subtracting 477 from 550 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 10:
The number 477 fits into 730 1 times, leaving a remainder of 253.
Put 1 as the next digit of the answer. 
Result so far: 160841.11
Subtracting 477 from 730 leaves us with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

The final outcome is 160841.11, with a leftover of 0.253.
