Let's divide 45479403 by 851
We want to figure out the number of times 45479403 can be divided by 851.

Step 1:
4 divided by 851 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 851

On to step 2:
851 goes into 45 0 times with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Grab the next digit (4) from the dividend, add it to 45, then carry on: 454 / 851

Let's proceed to step 3:
454 divided by 851 is 0 with a remainder of 454.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 454 after subtracting 0 from 454.
Fetch the next digit (7) from the dividend, attach it to 454 and continue: 4547 / 851

Moving on to step 4:
851 can be fit into 4547 5 times, resulting in a remainder of 292.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 292 after subtracting 4255 from 4547.
Bring next digit (9) of the dividend behind the 292 and repeat the process: 2929 / 851

Moving on to step 5:
851 goes into 2929 3 times with a remainder of 376.
The next digit of our result is 3. 
Result so far: 53.0
Deduct 2553 from 2929 and we're left with 376.
Include the next digit (4) from the dividend after 376, then repeat: 3764 / 851

Moving on to step 6:
851 goes into 3764 4 times with a remainder of 360.
The next digit of our result is 4. 
Result so far: 534.0
Subtract 3404 from 3764 to get 360.
Take the next digit (0) from the dividend and append it to 360, then repeat: 3600 / 851

Moving on to step 7:
851 can be fit into 3600 4 times, resulting in a remainder of 196.
The number 4 becomes the next digit in our result. 
Result so far: 5344.0
Subtract 3404 from 3600 to get 196.
Include the next digit (3) from the dividend after 196, then repeat: 1963 / 851

Moving on to step 8:
851 goes into 1963 2 times with a remainder of 261.
The next digit of our result is 2. 
Result so far: 53442.0
If we subtract 1702 from 1963, we get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Let's proceed to step 9:
851 goes into 2610 3 times with a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 53442.3
If we subtract 2553 from 2610, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 10:
The number 851 fits into 570 0 times, leaving a remainder of 570.
Use 0 as the next digit of our solution. 
Result so far: 53442.3
If we take 0 away from 570, we end up with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Let's proceed to step 11:
851 can be fit into 5700 6 times, resulting in a remainder of 594.
The number 6 becomes the next digit in our result. 
Result so far: 53442.306
Deduct 5106 from 5700 and we're left with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Going ahead to step 12:
851 can be fit into 5940 6 times, resulting in a remainder of 834.
Record the quotient 6 as the next digit in the result. 
Result so far: 53442.3066
If we subtract 5106 from 5940, we get 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

Our division results in 53442.3066 with a remaining 0.00834.
