19942 divided by 87 
We want to figure out the number of times 19942 can be divided by 87.

Going ahead to step 1:
1 divided by 87 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 87

Advancing to step 2:
The number 87 fits into 19 0 times, leaving a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 87

Advancing to step 3:
If we divide 199 by 87, we get 2 and a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 25 after subtracting 174 from 199.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 87

Going ahead to step 4:
87 can be fit into 254 2 times, resulting in a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 174 from 254 to get 80.
Take the next digit (2) from the dividend and append it to 80, then repeat: 802 / 87

Let's proceed to step 5:
87 can be fit into 802 9 times, resulting in a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 229.0
Subtracting 783 from 802 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 6:
If we divide 190 by 87, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 229.2
The remainder is 16 after subtracting 174 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
87 can be fit into 160 1 times, resulting in a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 229.21
Deduct 87 from 160 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 8:
87 goes into 730 8 times with a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 229.218
Subtracting 696 from 730 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
The number 87 fits into 340 3 times, leaving a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 229.2183
If we take 261 away from 340, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 10:
87 goes into 790 9 times with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 229.21839
Subtracting 783 from 790 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 11:
70 divided by 87 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 229.21839
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 12:
87 can be fit into 700 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 229.2183908
The remainder is 4 after subtracting 696 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
When dividing 40 by 87, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 229.2183908
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 229.2183908 and a remainder of 4e-08.
