1121987 divided by 42 
Let's see how many times 42 fits into 1121987.

Moving on to step 1:
42 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 42

Advancing to step 2:
42 goes into 11 0 times with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 42

Let's proceed to step 3:
42 can be fit into 112 2 times, resulting in a remainder of 28.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 84 from 112, we get 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 42

Step 4:
42 goes into 281 6 times with a remainder of 29.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we subtract 252 from 281, we get 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 42

Step 5:
The number 42 fits into 299 7 times, leaving a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 267.0
Subtracting 294 from 299 leaves us with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 42

Going ahead to step 6:
42 goes into 58 1 times with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 2671.0
Subtracting 42 from 58 leaves us with 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 42

Let's proceed to step 7:
The number 42 fits into 167 3 times, leaving a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 26713.0
Subtract 126 from 167 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 8:
42 can be fit into 410 9 times, resulting in a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 26713.9
If we take 378 away from 410, we end up 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.

Let's proceed to step 9:
When dividing 320 by 42, we get 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 26713.97
If we take 294 away from 320, we end up 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.

Advancing to step 10:
42 can be fit into 260 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 26713.976
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.

Step 11:
42 can be fit into 80 1 times, resulting in a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 26713.9761
Subtracting 42 from 80 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
380 divided by 42 is 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 26713.97619
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.

Let's proceed to step 13:
20 divided by 42 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 26713.97619
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
200 divided by 42 is 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 26713.9761904
If we take 168 away from 200, we end up 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.

Let's proceed to step 15:
320 divided by 42 is 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 26713.97619047
If we take 294 away from 320, we end up 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.

After the division, we end up with 26713.97619047 and a remainder of 2.6e-08.
