We look at the division of 291435 by 77 
We're looking to find how many times 77 goes into 291435.

Let's proceed to step 1:
77 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 77

Going ahead to step 2:
77 can be fit into 29 0 times, resulting in a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 77

On to step 3:
When dividing 291 by 77, we get 3 with a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 60 after subtracting 231 from 291.
Fetch the next digit (4) from the dividend, attach it to 60 and continue: 604 / 77

Let's proceed to step 4:
If we divide 604 by 77, we get 7 and a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we subtract 539 from 604, we get 65.
Include the next digit (3) from the dividend after 65, then repeat: 653 / 77

Going ahead to step 5:
The number 77 fits into 653 8 times, leaving a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 378.0
Subtracting 616 from 653 leaves us with 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 77

Going ahead to step 6:
77 can be fit into 375 4 times, resulting in a remainder of 67.
Record the quotient 4 as the next digit in the result. 
Result so far: 3784.0
Deduct 308 from 375 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 7:
670 divided by 77 is 8 with a remainder of 54.
The next digit of our result is 8. 
Result so far: 3784.8
Subtract 616 from 670 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 8:
77 goes into 540 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 3784.87
Subtract 539 from 540 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
When dividing 10 by 77, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 3784.87
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
The number 77 fits into 100 1 times, leaving a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 3784.8701
Subtracting 77 from 100 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 11:
If we divide 230 by 77, we get 2 and a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 3784.87012
If we subtract 154 from 230, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 12:
When dividing 760 by 77, we get 9 with a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 3784.870129
Deduct 693 from 760 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 13:
670 divided by 77 is 8 with a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 3784.8701298
If we take 616 away from 670, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 14:
77 can be fit into 540 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 3784.87012987
Subtract 539 from 540 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 3784.87012987, with a leftover of 1e-09.
