Let's divide 32907124 by 421
We want to divide 32907124 by 421.

On to step 1:
3 divided by 421 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 421

Moving on to step 2:
32 divided by 421 is 0 with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 32 and we're left with 32.
Append the next digit (9) from the dividend to 32 and continue with: 329 / 421

Step 3:
421 goes into 329 0 times with a remainder of 329.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 329 to get 329.
Append the next digit (0) from the dividend to 329 and continue with: 3290 / 421

Advancing to step 4:
421 can be fit into 3290 7 times, resulting in a remainder of 343.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 2947 from 3290 and we're left with 343.
Append the next digit (7) from the dividend to 343 and continue with: 3437 / 421

Step 5:
The number 421 fits into 3437 8 times, leaving a remainder of 69.
Write down 8 as next digit of the result. 
Result so far: 78.0
Subtracting 3368 from 3437 leaves us with 69.
Append the next digit (1) from the dividend to 69 and continue with: 691 / 421

Let's proceed to step 6:
The number 421 fits into 691 1 times, leaving a remainder of 270.
Write down 1 as next digit of the result. 
Result so far: 781.0
Subtract 421 from 691 to get 270.
Include the next digit (2) from the dividend after 270, then repeat: 2702 / 421

Step 7:
If we divide 2702 by 421, we get 6 and a remainder of 176.
The number 6 becomes the next digit in our result. 
Result so far: 7816.0
If we subtract 2526 from 2702, we get 176.
Append the next digit (4) from the dividend to 176 and continue with: 1764 / 421

Let's proceed to step 8:
1764 divided by 421 is 4 with a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 78164.0
If we take 1684 away from 1764, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 9:
When dividing 800 by 421, we get 1 with a remainder of 379.
The number 1 becomes the next digit in our result. 
Result so far: 78164.1
If we subtract 421 from 800, we get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Let's proceed to step 10:
3790 divided by 421 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 78164.19
If we take 3789 away from 3790, 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.

Going ahead to step 11:
10 divided by 421 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 78164.19
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
421 can be fit into 100 0 times, resulting in a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 78164.19
Subtract 0 from 100 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.

In conclusion, the division gives 78164.19 with a balance of 0.001.
