We're dividing 46378217 by 512 
We want to figure out the number of times 46378217 can be divided by 512.

On to step 1:
4 divided by 512 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 512

Step 2:
When dividing 46 by 512, we get 0 with a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 46 leaves us with 46.
Take the next digit (3) from the dividend and append it to 46, then repeat: 463 / 512

Let's proceed to step 3:
When dividing 463 by 512, we get 0 with a remainder of 463.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 463, we get 463.
Bring next digit (7) of the dividend behind the 463 and repeat the process: 4637 / 512

Step 4:
512 goes into 4637 9 times with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 4608 from 4637, we get 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 512

Going ahead to step 5:
512 can be fit into 298 0 times, resulting in a remainder of 298.
Use 0 as the next digit of our solution. 
Result so far: 90.0
The remainder is 298 after subtracting 0 from 298.
Take the next digit (2) from the dividend and append it to 298, then repeat: 2982 / 512

Advancing to step 6:
512 can be fit into 2982 5 times, resulting in a remainder of 422.
The next digit of our result is 5. 
Result so far: 905.0
Subtracting 2560 from 2982 leaves us with 422.
Grab the next digit (1) from the dividend, add it to 422, then carry on: 4221 / 512

Let's proceed to step 7:
If we divide 4221 by 512, we get 8 and a remainder of 125.
Write down 8 as next digit of the result. 
Result so far: 9058.0
Subtracting 4096 from 4221 leaves us with 125.
Take the next digit (7) from the dividend and append it to 125, then repeat: 1257 / 512

Moving on to step 8:
512 can be fit into 1257 2 times, resulting in a remainder of 233.
Write down 2 as next digit of the result. 
Result so far: 90582.0
Subtracting 1024 from 1257 leaves us with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Going ahead to step 9:
The number 512 fits into 2330 4 times, leaving a remainder of 282.
Put 4 as the next digit of the answer. 
Result so far: 90582.4
The remainder is 282 after subtracting 2048 from 2330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 10:
If we divide 2820 by 512, we get 5 and a remainder of 260.
Put 5 as the next digit of the answer. 
Result so far: 90582.45
Deduct 2560 from 2820 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 11:
512 can be fit into 2600 5 times, resulting in a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 90582.455
If we take 2560 away from 2600, 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.

The final outcome is 90582.455, with a leftover of 0.004.
