We look at the division of 8025710 by 421 
We're looking to find how many times 421 goes into 8025710.

Going ahead to step 1:
8 divided by 421 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 421

Going ahead to step 2:
421 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Append the next digit (2) from the dividend to 80 and continue with: 802 / 421

Moving on to step 3:
421 can be fit into 802 1 times, resulting in a remainder of 381.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 421 from 802, we get 381.
Bring next digit (5) of the dividend behind the 381 and repeat the process: 3815 / 421

Advancing to step 4:
If we divide 3815 by 421, we get 9 and a remainder of 26.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 3789 from 3815 to get 26.
Take the next digit (7) from the dividend and append it to 26, then repeat: 267 / 421

Advancing to step 5:
421 goes into 267 0 times with a remainder of 267.
Use 0 as the next digit of our solution. 
Result so far: 190.0
If we subtract 0 from 267, we get 267.
Fetch the next digit (1) from the dividend, attach it to 267 and continue: 2671 / 421

Let's proceed to step 6:
2671 divided by 421 is 6 with a remainder of 145.
Write down 6 as next digit of the result. 
Result so far: 1906.0
If we subtract 2526 from 2671, we get 145.
Bring next digit (0) of the dividend behind the 145 and repeat the process: 1450 / 421

Moving on to step 7:
421 goes into 1450 3 times with a remainder of 187.
The number 3 becomes the next digit in our result. 
Result so far: 19063.0
If we subtract 1263 from 1450, we get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Advancing to step 8:
When dividing 1870 by 421, we get 4 with a remainder of 186.
The next digit of our result is 4. 
Result so far: 19063.4
The remainder is 186 after subtracting 1684 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 9:
If we divide 1860 by 421, we get 4 and a remainder of 176.
Record the quotient 4 as the next digit in the result. 
Result so far: 19063.44
If we subtract 1684 from 1860, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

In conclusion, the division gives 19063.44 with a balance of 0.176.
