34210129 divided by 852 
Our goal is to divide 34210129 by 852.

Going ahead to step 1:
The number 852 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 852

Advancing to step 2:
852 goes into 34 0 times with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 852

Moving on to step 3:
852 goes into 342 0 times with a remainder of 342.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 342, we end up with 342.
Append the next digit (1) from the dividend to 342 and continue with: 3421 / 852

Let's proceed to step 4:
852 can be fit into 3421 4 times, resulting in a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 3408 from 3421 to get 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 852

Going ahead to step 5:
130 divided by 852 is 0 with a remainder of 130.
The next digit of our result is 0. 
Result so far: 40.0
Subtract 0 from 130 to get 130.
Grab the next digit (1) from the dividend, add it to 130, then carry on: 1301 / 852

Moving on to step 6:
The number 852 fits into 1301 1 times, leaving a remainder of 449.
The next digit of our result is 1. 
Result so far: 401.0
Subtract 852 from 1301 to get 449.
Grab the next digit (2) from the dividend, add it to 449, then carry on: 4492 / 852

Going ahead to step 7:
852 can be fit into 4492 5 times, resulting in a remainder of 232.
The number 5 becomes the next digit in our result. 
Result so far: 4015.0
Deduct 4260 from 4492 and we're left with 232.
Include the next digit (9) from the dividend after 232, then repeat: 2329 / 852

On to step 8:
2329 divided by 852 is 2 with a remainder of 625.
Put 2 as the next digit of the answer. 
Result so far: 40152.0
If we subtract 1704 from 2329, we get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Moving on to step 9:
852 goes into 6250 7 times with a remainder of 286.
The next digit of our result is 7. 
Result so far: 40152.7
Subtract 5964 from 6250 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 10:
If we divide 2860 by 852, we get 3 and a remainder of 304.
Write down 3 as next digit of the result. 
Result so far: 40152.73
Deduct 2556 from 2860 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 11:
3040 divided by 852 is 3 with a remainder of 484.
The number 3 becomes the next digit in our result. 
Result so far: 40152.733
Subtract 2556 from 3040 to get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

The final outcome is 40152.733, with a leftover of 0.0484.
