Let's divide 54210686 by 852
We're looking to find how many times 852 goes into 54210686.

Going ahead to step 1:
852 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 852

Going ahead to step 2:
54 divided by 852 is 0 with a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Include the next digit (2) from the dividend after 54, then repeat: 542 / 852

Step 3:
When dividing 542 by 852, we get 0 with a remainder of 542.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 542, we get 542.
Append the next digit (1) from the dividend to 542 and continue with: 5421 / 852

Moving on to step 4:
If we divide 5421 by 852, we get 6 and a remainder of 309.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 5112 from 5421 leaves us with 309.
Fetch the next digit (0) from the dividend, attach it to 309 and continue: 3090 / 852

Step 5:
3090 divided by 852 is 3 with a remainder of 534.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Deduct 2556 from 3090 and we're left with 534.
Include the next digit (6) from the dividend after 534, then repeat: 5346 / 852

Moving on to step 6:
852 can be fit into 5346 6 times, resulting in a remainder of 234.
Write down 6 as next digit of the result. 
Result so far: 636.0
Subtract 5112 from 5346 to get 234.
Take the next digit (8) from the dividend and append it to 234, then repeat: 2348 / 852

Going ahead to step 7:
The number 852 fits into 2348 2 times, leaving a remainder of 644.
Use 2 as the next digit of our solution. 
Result so far: 6362.0
If we take 1704 away from 2348, we end up with 644.
Fetch the next digit (6) from the dividend, attach it to 644 and continue: 6446 / 852

Going ahead to step 8:
852 can be fit into 6446 7 times, resulting in a remainder of 482.
Write down 7 as next digit of the result. 
Result so far: 63627.0
If we subtract 5964 from 6446, we get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Moving on to step 9:
4820 divided by 852 is 5 with a remainder of 560.
The number 5 becomes the next digit in our result. 
Result so far: 63627.5
Subtracting 4260 from 4820 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 10:
852 can be fit into 5600 6 times, resulting in a remainder of 488.
Record the quotient 6 as the next digit in the result. 
Result so far: 63627.56
Subtract 5112 from 5600 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Moving on to step 11:
If we divide 4880 by 852, we get 5 and a remainder of 620.
Use 5 as the next digit of our solution. 
Result so far: 63627.565
The remainder is 620 after subtracting 4260 from 4880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 12:
852 goes into 6200 7 times with a remainder of 236.
Write down 7 as next digit of the result. 
Result so far: 63627.5657
Subtract 5964 from 6200 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 13:
The number 852 fits into 2360 2 times, leaving a remainder of 656.
Write down 2 as next digit of the result. 
Result so far: 63627.56572
The remainder is 656 after subtracting 1704 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Moving on to step 14:
If we divide 6560 by 852, we get 7 and a remainder of 596.
The next digit of our result is 7. 
Result so far: 63627.565727
If we subtract 5964 from 6560, we get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 15:
The number 852 fits into 5960 6 times, leaving a remainder of 848.
Use 6 as the next digit of our solution. 
Result so far: 63627.5657276
Deduct 5112 from 5960 and we're left with 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

Advancing to step 16:
If we divide 8480 by 852, we get 9 and a remainder of 812.
Record the quotient 9 as the next digit in the result. 
Result so far: 63627.56572769
Subtract 7668 from 8480 to get 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

The final outcome is 63627.56572769, with a leftover of 8.12e-07.
