We look at the division of 25851485 by 470 
Our goal is to divide 25851485 by 470.

Going ahead to step 1:
The number 470 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 470

Moving on to step 2:
25 divided by 470 is 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 470

Step 3:
258 divided by 470 is 0 with a remainder of 258.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 258 and we're left with 258.
Bring next digit (5) of the dividend behind the 258 and repeat the process: 2585 / 470

Let's proceed to step 4:
The number 470 fits into 2585 5 times, leaving a remainder of 235.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 2350 from 2585 leaves us with 235.
Append the next digit (1) from the dividend to 235 and continue with: 2351 / 470

Let's proceed to step 5:
If we divide 2351 by 470, we get 5 and a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 55.0
The remainder is 1 after subtracting 2350 from 2351.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 470

Going ahead to step 6:
If we divide 14 by 470, we get 0 and a remainder of 14.
The next digit of our result is 0. 
Result so far: 550.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 470

On to step 7:
If we divide 148 by 470, we get 0 and a remainder of 148.
The next digit of our result is 0. 
Result so far: 5500.0
Subtracting 0 from 148 leaves us with 148.
Take the next digit (5) from the dividend and append it to 148, then repeat: 1485 / 470

On to step 8:
When dividing 1485 by 470, we get 3 with a remainder of 75.
The next digit of our result is 3. 
Result so far: 55003.0
Subtracting 1410 from 1485 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 9:
When dividing 750 by 470, we get 1 with a remainder of 280.
Record the quotient 1 as the next digit in the result. 
Result so far: 55003.1
Deduct 470 from 750 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 10:
The number 470 fits into 2800 5 times, leaving a remainder of 450.
Write down 5 as next digit of the result. 
Result so far: 55003.15
If we take 2350 away from 2800, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 11:
When dividing 4500 by 470, we get 9 with a remainder of 270.
Record the quotient 9 as the next digit in the result. 
Result so far: 55003.159
The remainder is 270 after subtracting 4230 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 12:
The number 470 fits into 2700 5 times, leaving a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 55003.1595
Deduct 2350 from 2700 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 13:
If we divide 3500 by 470, we get 7 and a remainder of 210.
The number 7 becomes the next digit in our result. 
Result so far: 55003.15957
Subtracting 3290 from 3500 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 14:
The number 470 fits into 2100 4 times, leaving a remainder of 220.
Put 4 as the next digit of the answer. 
Result so far: 55003.159574
Subtracting 1880 from 2100 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 15:
2200 divided by 470 is 4 with a remainder of 320.
Write down 4 as next digit of the result. 
Result so far: 55003.1595744
Subtract 1880 from 2200 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final outcome is 55003.1595744, with a leftover of 3.2e-06.
