We're dividing 436542 by 77 
Let's see how many times 77 fits into 436542.

Going ahead to step 1:
When dividing 4 by 77, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 77

On to step 2:
The number 77 fits into 43 0 times, leaving a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Append the next digit (6) from the dividend to 43 and continue with: 436 / 77

On to step 3:
If we divide 436 by 77, we get 5 and a remainder of 51.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 385 from 436, we get 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 77

Step 4:
77 can be fit into 515 6 times, resulting in a remainder of 53.
The next digit of our result is 6. 
Result so far: 56.0
If we take 462 away from 515, we end up with 53.
Fetch the next digit (4) from the dividend, attach it to 53 and continue: 534 / 77

On to step 5:
77 can be fit into 534 6 times, resulting in a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 566.0
If we subtract 462 from 534, we get 72.
Grab the next digit (2) from the dividend, add it to 72, then carry on: 722 / 77

On to step 6:
If we divide 722 by 77, we get 9 and a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 5669.0
The remainder is 29 after subtracting 693 from 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
77 can be fit into 290 3 times, resulting in a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 5669.3
Subtract 231 from 290 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 8:
If we divide 590 by 77, we get 7 and a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 5669.37
Subtract 539 from 590 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 9:
510 divided by 77 is 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 5669.376
Subtract 462 from 510 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
480 divided by 77 is 6 with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 5669.3766
If we take 462 away from 480, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 5669.3766, with a leftover of 0.00018.
