157887 ÷ 42 
We want to figure out the number of times 157887 can be divided by 42.

Moving on to step 1:
The number 42 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 42

Advancing to step 2:
42 goes into 15 0 times with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 42

Advancing to step 3:
The number 42 fits into 157 3 times, leaving a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 126 away from 157, we end up with 31.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 42

Let's proceed to step 4:
When dividing 318 by 42, we get 7 with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Subtract 294 from 318 to get 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 42

Let's proceed to step 5:
If we divide 248 by 42, we get 5 and a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 375.0
The remainder is 38 after subtracting 210 from 248.
Fetch the next digit (7) from the dividend, attach it to 38 and continue: 387 / 42

Advancing to step 6:
42 goes into 387 9 times with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 3759.0
The remainder is 9 after subtracting 378 from 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
When dividing 90 by 42, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 3759.2
If we take 84 away from 90, we end up 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.

Moving on to step 8:
The number 42 fits into 60 1 times, leaving a remainder of 18.
The next digit of our result is 1. 
Result so far: 3759.21
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.

Let's proceed to step 9:
180 divided by 42 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 3759.214
If we subtract 168 from 180, we 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.

Going ahead to step 10:
120 divided by 42 is 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 3759.2142
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.

On to step 11:
42 goes into 360 8 times with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 3759.21428
Deduct 336 from 360 and we're left 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.

Going ahead to step 12:
42 goes into 240 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 3759.214285
Subtract 210 from 240 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
When dividing 300 by 42, we get 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 3759.2142857
If we take 294 away from 300, we end up 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.

Advancing to step 14:
When dividing 60 by 42, we get 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 3759.21428571
If we take 42 away from 60, we end up 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.

The quotient of the division is 3759.21428571, and the remainder is 1.8e-08.
