60558221 divided by 421 
Let's see how many times 421 fits into 60558221.

Let's proceed to step 1:
If we divide 6 by 421, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 421

Moving on to step 2:
When dividing 60 by 421, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Bring next digit (5) of the dividend behind the 60 and repeat the process: 605 / 421

Let's proceed to step 3:
421 goes into 605 1 times with a remainder of 184.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 421 away from 605, we end up with 184.
Take the next digit (5) from the dividend and append it to 184, then repeat: 1845 / 421

On to step 4:
1845 divided by 421 is 4 with a remainder of 161.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 1684 from 1845, we get 161.
Fetch the next digit (8) from the dividend, attach it to 161 and continue: 1618 / 421

Advancing to step 5:
421 can be fit into 1618 3 times, resulting in a remainder of 355.
Use 3 as the next digit of our solution. 
Result so far: 143.0
Deduct 1263 from 1618 and we're left with 355.
Fetch the next digit (2) from the dividend, attach it to 355 and continue: 3552 / 421

On to step 6:
When dividing 3552 by 421, we get 8 with a remainder of 184.
Write down 8 as next digit of the result. 
Result so far: 1438.0
Subtract 3368 from 3552 to get 184.
Grab the next digit (2) from the dividend, add it to 184, then carry on: 1842 / 421

Advancing to step 7:
421 can be fit into 1842 4 times, resulting in a remainder of 158.
Write down 4 as next digit of the result. 
Result so far: 14384.0
The remainder is 158 after subtracting 1684 from 1842.
Fetch the next digit (1) from the dividend, attach it to 158 and continue: 1581 / 421

Step 8:
When dividing 1581 by 421, we get 3 with a remainder of 318.
The number 3 becomes the next digit in our result. 
Result so far: 143843.0
Subtracting 1263 from 1581 leaves us with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Step 9:
3180 divided by 421 is 7 with a remainder of 233.
The next digit of our result is 7. 
Result so far: 143843.7
If we take 2947 away from 3180, we end up with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Going ahead to step 10:
421 goes into 2330 5 times with a remainder of 225.
The next digit of our result is 5. 
Result so far: 143843.75
Deduct 2105 from 2330 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 11:
The number 421 fits into 2250 5 times, leaving a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 143843.755
If we take 2105 away from 2250, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final result is 143843.755 with a remainder of 0.0145.
