We look at the division of 901239 by 46 
We're looking to find how many times 46 goes into 901239.

Going ahead to step 1:
46 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 46

On to step 2:
The number 46 fits into 90 1 times, leaving a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 46 from 90 leaves us with 44.
Include the next digit (1) from the dividend after 44, then repeat: 441 / 46

Going ahead to step 3:
When dividing 441 by 46, we get 9 with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 414 from 441 leaves us with 27.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 46

Advancing to step 4:
The number 46 fits into 272 5 times, leaving a remainder of 42.
Put 5 as the next digit of the answer. 
Result so far: 195.0
Subtracting 230 from 272 leaves us with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 46

Going ahead to step 5:
46 can be fit into 423 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 1959.0
The remainder is 9 after subtracting 414 from 423.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 46

Moving on to step 6:
46 can be fit into 99 2 times, resulting in a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 19592.0
Subtracting 92 from 99 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.

Going ahead to step 7:
46 goes into 70 1 times with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 19592.1
If we subtract 46 from 70, we get 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 8:
46 can be fit into 240 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 19592.15
Subtract 230 from 240 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
100 divided by 46 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 19592.152
Subtracting 92 from 100 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 10:
80 divided by 46 is 1 with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 19592.1521
Subtracting 46 from 80 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.

Step 11:
When dividing 340 by 46, we get 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 19592.15217
Deduct 322 from 340 and we're left 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.

Step 12:
46 can be fit into 180 3 times, resulting in a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 19592.152173
Deduct 138 from 180 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
The number 46 fits into 420 9 times, leaving a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 19592.1521739
The remainder is 6 after subtracting 414 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
If we divide 60 by 46, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 19592.15217391
If we take 46 away from 60, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 19592.15217391, with a leftover of 1.4e-08.
