We look at the division of 25430859 by 350 
We want to divide 25430859 by 350.

On to step 1:
350 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 350

Moving on to step 2:
350 goes into 25 0 times with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Bring next digit (4) of the dividend behind the 25 and repeat the process: 254 / 350

On to step 3:
When dividing 254 by 350, we get 0 with a remainder of 254.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 254 leaves us with 254.
Include the next digit (3) from the dividend after 254, then repeat: 2543 / 350

Step 4:
350 goes into 2543 7 times with a remainder of 93.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 2450 from 2543, we get 93.
Append the next digit (0) from the dividend to 93 and continue with: 930 / 350

Step 5:
When dividing 930 by 350, we get 2 with a remainder of 230.
Write down 2 as next digit of the result. 
Result so far: 72.0
If we subtract 700 from 930, we get 230.
Fetch the next digit (8) from the dividend, attach it to 230 and continue: 2308 / 350

Step 6:
When dividing 2308 by 350, we get 6 with a remainder of 208.
Use 6 as the next digit of our solution. 
Result so far: 726.0
If we take 2100 away from 2308, we end up with 208.
Append the next digit (5) from the dividend to 208 and continue with: 2085 / 350

Let's proceed to step 7:
When dividing 2085 by 350, we get 5 with a remainder of 335.
The next digit of our result is 5. 
Result so far: 7265.0
If we subtract 1750 from 2085, we get 335.
Bring next digit (9) of the dividend behind the 335 and repeat the process: 3359 / 350

On to step 8:
3359 divided by 350 is 9 with a remainder of 209.
Put 9 as the next digit of the answer. 
Result so far: 72659.0
Deduct 3150 from 3359 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Advancing to step 9:
350 can be fit into 2090 5 times, resulting in a remainder of 340.
The next digit of our result is 5. 
Result so far: 72659.5
Subtract 1750 from 2090 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 10:
3400 divided by 350 is 9 with a remainder of 250.
The next digit of our result is 9. 
Result so far: 72659.59
If we subtract 3150 from 3400, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 11:
If we divide 2500 by 350, we get 7 and a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 72659.597
The remainder is 50 after subtracting 2450 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
When dividing 500 by 350, we get 1 with a remainder of 150.
Record the quotient 1 as the next digit in the result. 
Result so far: 72659.5971
The remainder is 150 after subtracting 350 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 13:
The number 350 fits into 1500 4 times, leaving a remainder of 100.
The next digit of our result is 4. 
Result so far: 72659.59714
Subtract 1400 from 1500 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 14:
The number 350 fits into 1000 2 times, leaving a remainder of 300.
The next digit of our result is 2. 
Result so far: 72659.597142
If we take 700 away from 1000, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 15:
350 can be fit into 3000 8 times, resulting in a remainder of 200.
Use 8 as the next digit of our solution. 
Result so far: 72659.5971428
If we take 2800 away from 3000, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 16:
2000 divided by 350 is 5 with a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 72659.59714285
Deduct 1750 from 2000 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The quotient of the division is 72659.59714285, and the remainder is 2.5e-07.
