We divide 258402 by 77
We want to divide 258402 by 77.

Let's proceed to step 1:
77 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 77

Moving on to step 2:
When dividing 25 by 77, we get 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 77

Let's proceed to step 3:
77 goes into 258 3 times with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 231 from 258 and we're left with 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 77

Moving on to step 4:
77 goes into 274 3 times with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we take 231 away from 274, we end up with 43.
Include the next digit (0) from the dividend after 43, then repeat: 430 / 77

Going ahead to step 5:
The number 77 fits into 430 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 335.0
If we subtract 385 from 430, we get 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 77

Advancing to step 6:
If we divide 452 by 77, we get 5 and a remainder of 67.
Write down 5 as next digit of the result. 
Result so far: 3355.0
Deduct 385 from 452 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.

Going ahead to step 7:
The number 77 fits into 670 8 times, leaving a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 3355.8
The remainder is 54 after subtracting 616 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 8:
77 can be fit into 540 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 3355.87
The remainder is 1 after subtracting 539 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
77 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 3355.87
If we subtract 0 from 10, we 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.
Use 1 as the next digit of our solution. 
Result so far: 3355.8701
If we subtract 77 from 100, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 11:
77 goes into 230 2 times with a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 3355.87012
Subtracting 154 from 230 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
77 can be fit into 760 9 times, resulting in a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 3355.870129
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.

Advancing to step 13:
77 goes into 670 8 times with a remainder of 54.
The next digit of our result is 8. 
Result so far: 3355.8701298
Subtracting 616 from 670 leaves us 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.

Going ahead to step 14:
77 can be fit into 540 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 3355.87012987
If we take 539 away from 540, we end up with 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 3355.87012987, with a leftover of 1e-09.
