58554081 ÷ 420 
Let's see how many times 420 fits into 58554081.

Moving on to step 1:
420 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 420

Step 2:
If we divide 58 by 420, we get 0 and a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Include the next digit (5) from the dividend after 58, then repeat: 585 / 420

Moving on to step 3:
585 divided by 420 is 1 with a remainder of 165.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 420 away from 585, we end up with 165.
Include the next digit (5) from the dividend after 165, then repeat: 1655 / 420

On to step 4:
When dividing 1655 by 420, we get 3 with a remainder of 395.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 395 after subtracting 1260 from 1655.
Append the next digit (4) from the dividend to 395 and continue with: 3954 / 420

Step 5:
The number 420 fits into 3954 9 times, leaving a remainder of 174.
Write down 9 as next digit of the result. 
Result so far: 139.0
If we take 3780 away from 3954, we end up with 174.
Include the next digit (0) from the dividend after 174, then repeat: 1740 / 420

Advancing to step 6:
If we divide 1740 by 420, we get 4 and a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 1394.0
If we subtract 1680 from 1740, we get 60.
Take the next digit (8) from the dividend and append it to 60, then repeat: 608 / 420

Going ahead to step 7:
When dividing 608 by 420, we get 1 with a remainder of 188.
Put 1 as the next digit of the answer. 
Result so far: 13941.0
Deduct 420 from 608 and we're left with 188.
Fetch the next digit (1) from the dividend, attach it to 188 and continue: 1881 / 420

On to step 8:
If we divide 1881 by 420, we get 4 and a remainder of 201.
The next digit of our result is 4. 
Result so far: 139414.0
Subtracting 1680 from 1881 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 9:
420 can be fit into 2010 4 times, resulting in a remainder of 330.
Put 4 as the next digit of the answer. 
Result so far: 139414.4
If we subtract 1680 from 2010, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 10:
3300 divided by 420 is 7 with a remainder of 360.
The next digit of our result is 7. 
Result so far: 139414.47
The remainder is 360 after subtracting 2940 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 11:
420 can be fit into 3600 8 times, resulting in a remainder of 240.
Write down 8 as next digit of the result. 
Result so far: 139414.478
The remainder is 240 after subtracting 3360 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 12:
If we divide 2400 by 420, we get 5 and a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 139414.4785
Deduct 2100 from 2400 and we're left 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.

Advancing to step 13:
420 goes into 3000 7 times with a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 139414.47857
Subtract 2940 from 3000 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
When dividing 600 by 420, we get 1 with a remainder of 180.
Record the quotient 1 as the next digit in the result. 
Result so far: 139414.478571
The remainder is 180 after subtracting 420 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 15:
420 goes into 1800 4 times with a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 139414.4785714
Subtracting 1680 from 1800 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 16:
When dividing 1200 by 420, we get 2 with a remainder of 360.
Write down 2 as next digit of the result. 
Result so far: 139414.47857142
The remainder is 360 after subtracting 840 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The final result is 139414.47857142 with a remainder of 3.6e-07.
