We look at the division of 45168685 by 50 
We want to figure out the number of times 45168685 can be divided by 50.

Advancing to step 1:
When dividing 4 by 50, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 50

On to step 2:
50 goes into 45 0 times with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 50

Step 3:
The number 50 fits into 451 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 1 after subtracting 450 from 451.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 50

Going ahead to step 4:
The number 50 fits into 16 0 times, leaving a remainder of 16.
The next digit of our result is 0. 
Result so far: 90.0
Subtract 0 from 16 to get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 50

Moving on to step 5:
If we divide 168 by 50, we get 3 and a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 903.0
If we subtract 150 from 168, we get 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 50

Going ahead to step 6:
186 divided by 50 is 3 with a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 9033.0
If we take 150 away from 186, we end up with 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 50

Let's proceed to step 7:
50 can be fit into 368 7 times, resulting in a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 90337.0
Subtracting 350 from 368 leaves us with 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 50

Let's proceed to step 8:
50 can be fit into 185 3 times, resulting in a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 903373.0
If we subtract 150 from 185, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
50 can be fit into 350 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 903373.7
Subtract 350 from 350 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
0 divided by 50 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 903373.7
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
0 divided by 50 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 903373.7
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 903373.7, with a leftover of 0.0.
