Let's divide 406053 by 42
We want to divide 406053 by 42.

Advancing to step 1:
If we divide 4 by 42, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 42

On to step 2:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 42

Moving on to step 3:
If we divide 406 by 42, we get 9 and a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 378 from 406, we get 28.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 42

Let's proceed to step 4:
The number 42 fits into 280 6 times, leaving a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
Deduct 252 from 280 and we're left with 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 42

Advancing to step 5:
If we divide 285 by 42, we get 6 and a remainder of 33.
Record the quotient 6 as the next digit in the result. 
Result so far: 966.0
Subtracting 252 from 285 leaves us with 33.
Include the next digit (3) from the dividend after 33, then repeat: 333 / 42

Going ahead to step 6:
The number 42 fits into 333 7 times, leaving a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 9667.0
The remainder is 39 after subtracting 294 from 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
42 goes into 390 9 times with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 9667.9
Subtract 378 from 390 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
If we divide 120 by 42, we get 2 and a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 9667.92
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
If we divide 360 by 42, we get 8 and a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 9667.928
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
When dividing 240 by 42, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 9667.9285
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
When dividing 300 by 42, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 9667.92857
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 9667.928571
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
42 goes into 180 4 times with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 9667.9285714
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
When dividing 120 by 42, we get 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 9667.92857142
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 9667.92857142 with a remainder of 3.6e-08.
