We look at the division of 401405 by 42 
We want to divide 401405 by 42.

Advancing to step 1:
42 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 42

On to step 2:
42 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 42

Advancing to step 3:
42 can be fit into 401 9 times, resulting in a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 378 from 401 and we're left with 23.
Fetch the next digit (4) from the dividend, attach it to 23 and continue: 234 / 42

Let's proceed to step 4:
If we divide 234 by 42, we get 5 and a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
Subtract 210 from 234 to get 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 42

Moving on to step 5:
42 goes into 240 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 955.0
Subtract 210 from 240 to get 30.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 42

Let's proceed to step 6:
The number 42 fits into 305 7 times, leaving a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 9557.0
Subtracting 294 from 305 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
42 can be fit into 110 2 times, resulting in a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 9557.2
Subtract 84 from 110 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
260 divided by 42 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 9557.26
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 9557.261
The remainder is 38 after subtracting 42 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
42 goes into 380 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 9557.2619
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
When dividing 20 by 42, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 9557.2619
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
200 divided by 42 is 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 9557.261904
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
If we divide 320 by 42, we get 7 and a remainder of 26.
The next digit of our result is 7. 
Result so far: 9557.2619047
Subtracting 294 from 320 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
260 divided by 42 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 9557.26190476
Subtracting 252 from 260 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 9557.26190476 with a balance of 8e-09.
