We're dividing 12250465 by 42 
Let's see how many times 42 fits into 12250465.

Let's proceed to step 1:
If we divide 1 by 42, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 42

Step 2:
The number 42 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 42

Let's proceed to step 3:
42 can be fit into 122 2 times, resulting in a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 38 after subtracting 84 from 122.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 42

Let's proceed to step 4:
42 can be fit into 385 9 times, resulting in a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we take 378 away from 385, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 42

On to step 5:
42 can be fit into 70 1 times, resulting in a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 291.0
If we take 42 away from 70, we end up with 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 42

Advancing to step 6:
42 can be fit into 284 6 times, resulting in a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 2916.0
The remainder is 32 after subtracting 252 from 284.
Grab the next digit (6) from the dividend, add it to 32, then carry on: 326 / 42

Advancing to step 7:
42 goes into 326 7 times with a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 29167.0
Subtracting 294 from 326 leaves us with 32.
Bring next digit (5) of the dividend behind the 32 and repeat the process: 325 / 42

Advancing to step 8:
42 can be fit into 325 7 times, resulting in a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 291677.0
Subtracting 294 from 325 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
When dividing 310 by 42, we get 7 with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 291677.7
Deduct 294 from 310 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 291677.73
Subtracting 126 from 160 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.

Let's proceed to step 11:
340 divided by 42 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 291677.738
If we subtract 336 from 340, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
If we divide 40 by 42, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 291677.738
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
42 goes into 400 9 times with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 291677.73809
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
220 divided by 42 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 291677.738095
Deduct 210 from 220 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 15:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 291677.7380952
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 16:
If we divide 160 by 42, we get 3 and a remainder of 34.
The next digit of our result is 3. 
Result so far: 291677.73809523
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The quotient of the division is 291677.73809523, and the remainder is 3.4e-08.
