We look at the division of 15421625 by 46 
We're looking to find how many times 46 goes into 15421625.

Moving on to step 1:
The number 46 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 46

Going ahead to step 2:
When dividing 15 by 46, we get 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 46

On to step 3:
When dividing 154 by 46, we get 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 138 from 154 leaves us with 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 46

On to step 4:
If we divide 162 by 46, we get 3 and a remainder of 24.
The next digit of our result is 3. 
Result so far: 33.0
The remainder is 24 after subtracting 138 from 162.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 46

Step 5:
46 goes into 241 5 times with a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 335.0
If we subtract 230 from 241, we get 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 46

Going ahead to step 6:
116 divided by 46 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 3352.0
If we subtract 92 from 116, we get 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 46

Let's proceed to step 7:
When dividing 242 by 46, we get 5 with a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 33525.0
Subtract 230 from 242 to get 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 46

On to step 8:
46 goes into 125 2 times with a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 335252.0
The remainder is 33 after subtracting 92 from 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 9:
330 divided by 46 is 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 335252.7
Deduct 322 from 330 and we're left 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.

Going ahead to step 10:
When dividing 80 by 46, we get 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 335252.71
If we subtract 46 from 80, we get 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:
46 can be fit into 340 7 times, resulting in a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 335252.717
The remainder is 18 after subtracting 322 from 340.
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 12:
46 goes into 180 3 times with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 335252.7173
Subtracting 138 from 180 leaves us 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.

On to step 13:
46 can be fit into 420 9 times, resulting in a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 335252.71739
Subtracting 414 from 420 leaves us 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 14:
When dividing 60 by 46, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 335252.717391
Deduct 46 from 60 and we're left 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.

Advancing to step 15:
46 can be fit into 140 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 335252.7173913
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 16:
If we divide 20 by 46, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 335252.7173913
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 335252.7173913, with a leftover of 2e-08.
