Let's divide 45135029 by 854
We're looking to find how many times 854 goes into 45135029.

Going ahead to step 1:
854 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 854

On to step 2:
The number 854 fits into 45 0 times, leaving a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 854

On to step 3:
451 divided by 854 is 0 with a remainder of 451.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 451, we get 451.
Take the next digit (3) from the dividend and append it to 451, then repeat: 4513 / 854

Let's proceed to step 4:
When dividing 4513 by 854, we get 5 with a remainder of 243.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 243 after subtracting 4270 from 4513.
Bring next digit (5) of the dividend behind the 243 and repeat the process: 2435 / 854

Moving on to step 5:
854 goes into 2435 2 times with a remainder of 727.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
Subtracting 1708 from 2435 leaves us with 727.
Fetch the next digit (0) from the dividend, attach it to 727 and continue: 7270 / 854

Step 6:
7270 divided by 854 is 8 with a remainder of 438.
Record the quotient 8 as the next digit in the result. 
Result so far: 528.0
Subtracting 6832 from 7270 leaves us with 438.
Grab the next digit (2) from the dividend, add it to 438, then carry on: 4382 / 854

Step 7:
If we divide 4382 by 854, we get 5 and a remainder of 112.
The number 5 becomes the next digit in our result. 
Result so far: 5285.0
Deduct 4270 from 4382 and we're left with 112.
Bring next digit (9) of the dividend behind the 112 and repeat the process: 1129 / 854

On to step 8:
854 goes into 1129 1 times with a remainder of 275.
Record the quotient 1 as the next digit in the result. 
Result so far: 52851.0
If we take 854 away from 1129, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 9:
If we divide 2750 by 854, we get 3 and a remainder of 188.
The next digit of our result is 3. 
Result so far: 52851.3
Subtracting 2562 from 2750 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 10:
854 goes into 1880 2 times with a remainder of 172.
The number 2 becomes the next digit in our result. 
Result so far: 52851.32
Subtracting 1708 from 1880 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 11:
1720 divided by 854 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 52851.322
If we take 1708 away from 1720, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 52851.322, with a leftover of 0.0012.
