We look at the division of 53450021 by 852 
We want to figure out the number of times 53450021 can be divided by 852.

Advancing to step 1:
5 divided by 852 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 852

Step 2:
852 goes into 53 0 times with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Fetch the next digit (4) from the dividend, attach it to 53 and continue: 534 / 852

Going ahead to step 3:
852 can be fit into 534 0 times, resulting in a remainder of 534.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 534 to get 534.
Grab the next digit (5) from the dividend, add it to 534, then carry on: 5345 / 852

Advancing to step 4:
5345 divided by 852 is 6 with a remainder of 233.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 5112 from 5345, we get 233.
Append the next digit (0) from the dividend to 233 and continue with: 2330 / 852

Let's proceed to step 5:
If we divide 2330 by 852, we get 2 and a remainder of 626.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
If we take 1704 away from 2330, we end up with 626.
Take the next digit (0) from the dividend and append it to 626, then repeat: 6260 / 852

On to step 6:
If we divide 6260 by 852, we get 7 and a remainder of 296.
Put 7 as the next digit of the answer. 
Result so far: 627.0
The remainder is 296 after subtracting 5964 from 6260.
Append the next digit (2) from the dividend to 296 and continue with: 2962 / 852

Step 7:
When dividing 2962 by 852, we get 3 with a remainder of 406.
Use 3 as the next digit of our solution. 
Result so far: 6273.0
The remainder is 406 after subtracting 2556 from 2962.
Take the next digit (1) from the dividend and append it to 406, then repeat: 4061 / 852

On to step 8:
4061 divided by 852 is 4 with a remainder of 653.
The next digit of our result is 4. 
Result so far: 62734.0
Subtracting 3408 from 4061 leaves us with 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Going ahead to step 9:
852 goes into 6530 7 times with a remainder of 566.
Record the quotient 7 as the next digit in the result. 
Result so far: 62734.7
Subtracting 5964 from 6530 leaves us with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Step 10:
852 can be fit into 5660 6 times, resulting in a remainder of 548.
The next digit of our result is 6. 
Result so far: 62734.76
The remainder is 548 after subtracting 5112 from 5660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Let's proceed to step 11:
The number 852 fits into 5480 6 times, leaving a remainder of 368.
The number 6 becomes the next digit in our result. 
Result so far: 62734.766
If we take 5112 away from 5480, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

After the division, we end up with 62734.766 and a remainder of 0.0368.
