621754 ÷ 42 
Our goal is to divide 621754 by 42.

Let's proceed to step 1:
The number 42 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 42

Advancing to step 2:
The number 42 fits into 62 1 times, leaving a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 42 from 62, we get 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 42

Going ahead to step 3:
If we divide 201 by 42, we get 4 and a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 168 from 201 leaves us with 33.
Fetch the next digit (7) from the dividend, attach it to 33 and continue: 337 / 42

Let's proceed to step 4:
42 can be fit into 337 8 times, resulting in a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
If we subtract 336 from 337, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 42

Advancing to step 5:
42 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 1480.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 42

Let's proceed to step 6:
42 can be fit into 154 3 times, resulting in a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 14803.0
Deduct 126 from 154 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 7:
When dividing 280 by 42, we get 6 with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 14803.6
If we take 252 away from 280, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
42 goes into 280 6 times with a remainder of 28.
The next digit of our result is 6. 
Result so far: 14803.66
Subtracting 252 from 280 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 14803.66 with a balance of 0.028.
