We divide 160641 by 42
We want to figure out the number of times 160641 can be divided by 42.

Advancing to step 1:
1 divided by 42 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 42

Advancing to step 2:
42 can be fit into 16 0 times, resulting in a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 42

Let's proceed to step 3:
160 divided by 42 is 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 34 after subtracting 126 from 160.
Take the next digit (6) from the dividend and append it to 34, then repeat: 346 / 42

On to step 4:
42 can be fit into 346 8 times, resulting in a remainder of 10.
The next digit of our result is 8. 
Result so far: 38.0
Subtracting 336 from 346 leaves us with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 42

Advancing to step 5:
42 can be fit into 104 2 times, resulting in a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 382.0
Deduct 84 from 104 and we're left with 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 42

Going ahead to step 6:
When dividing 201 by 42, we get 4 with a remainder of 33.
The number 4 becomes the next digit in our result. 
Result so far: 3824.0
If we take 168 away from 201, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
When dividing 330 by 42, we get 7 with a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 3824.7
Deduct 294 from 330 and we're left 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.

Moving on to step 8:
360 divided by 42 is 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 3824.78
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.

Moving on to step 9:
When dividing 240 by 42, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 3824.785
If we take 210 away from 240, we end up 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 10:
300 divided by 42 is 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 3824.7857
Subtracting 294 from 300 leaves us with 6.
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 11:
When dividing 60 by 42, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 3824.78571
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
180 divided by 42 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 3824.785714
Subtracting 168 from 180 leaves us 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.

Advancing to step 13:
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: 3824.7857142
Deduct 84 from 120 and we're left 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.

Going ahead to step 14:
42 goes into 360 8 times with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 3824.78571428
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 3824.78571428 with a balance of 2.4e-08.
