25709870 divided by 77 
We want to divide 25709870 by 77.

Advancing to step 1:
77 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 77

Let's proceed to step 2:
77 can be fit into 25 0 times, resulting in a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Include the next digit (7) from the dividend after 25, then repeat: 257 / 77

Advancing to step 3:
257 divided by 77 is 3 with a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 231 away from 257, we end up with 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 77

Moving on to step 4:
The number 77 fits into 260 3 times, leaving a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we take 231 away from 260, we end up with 29.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 77

On to step 5:
299 divided by 77 is 3 with a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 333.0
If we subtract 231 from 299, we get 68.
Grab the next digit (8) from the dividend, add it to 68, then carry on: 688 / 77

Moving on to step 6:
If we divide 688 by 77, we get 8 and a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 3338.0
The remainder is 72 after subtracting 616 from 688.
Take the next digit (7) from the dividend and append it to 72, then repeat: 727 / 77

Advancing to step 7:
The number 77 fits into 727 9 times, leaving a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 33389.0
If we take 693 away from 727, we end up with 34.
Fetch the next digit (0) from the dividend, attach it to 34 and continue: 340 / 77

On to step 8:
340 divided by 77 is 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 333894.0
Deduct 308 from 340 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
320 divided by 77 is 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 333894.4
If we take 308 away from 320, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
If we divide 120 by 77, we get 1 and a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 333894.41
The remainder is 43 after subtracting 77 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 11:
If we divide 430 by 77, we get 5 and a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 333894.415
If we subtract 385 from 430, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 12:
77 can be fit into 450 5 times, resulting in a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 333894.4155
If we take 385 away from 450, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 333894.4155 with a remainder of 0.00065.
