Going ahead to step 3:
853 can be fit into 868 1 times, resulting in a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 853 from 868 to get 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 853

Let's proceed to step 4:
156 divided by 853 is 0 with a remainder of 156.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 156 to get 156.
Include the next digit (7) from the dividend after 156, then repeat: 1567 / 853

Advancing to step 5:
When dividing 1567 by 853, we get 1 with a remainder of 714.
The next digit of our result is 1. 
Result so far: 101.0
Subtracting 853 from 1567 leaves us with 714.
Grab the next digit (7) from the dividend, add it to 714, then carry on: 7147 / 853

On to step 6:
The number 853 fits into 7147 8 times, leaving a remainder of 323.
The next digit of our result is 8. 
Result so far: 1018.0
Subtract 6824 from 7147 to get 323.
Include the next digit (5) from the dividend after 323, then repeat: 3235 / 853

Step 7:
853 goes into 3235 3 times with a remainder of 676.
Record the quotient 3 as the next digit in the result. 
Result so far: 10183.0
Subtracting 2559 from 3235 leaves us with 676.
Fetch the next digit (8) from the dividend, attach it to 676 and continue: 6768 / 853

Moving on to step 8:
853 can be fit into 6768 7 times, resulting in a remainder of 797.
Put 7 as the next digit of the answer. 
Result so far: 101837.0
Subtract 5971 from 6768 to get 797.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7970, and continue the process.

Step 9:
853 can be fit into 7970 9 times, resulting in a remainder of 293.
The number 9 becomes the next digit in our result. 
Result so far: 101837.9
Deduct 7677 from 7970 and we're left with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Moving on to step 10:
The number 853 fits into 2930 3 times, leaving a remainder of 371.
Put 3 as the next digit of the answer. 
Result so far: 101837.93
If we take 2559 away from 2930, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Advancing to step 11:
When dividing 3710 by 853, we get 4 with a remainder of 298.
Record the quotient 4 as the next digit in the result. 
Result so far: 101837.934
If we take 3412 away from 3710, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 12:
When dividing 2980 by 853, we get 3 with a remainder of 421.
The number 3 becomes the next digit in our result. 
Result so far: 101837.9343
If we subtract 2559 from 2980, we get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Moving on to step 13:
The number 853 fits into 4210 4 times, leaving a remainder of 798.
Put 4 as the next digit of the answer. 
Result so far: 101837.93434
Subtracting 3412 from 4210 leaves us with 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Moving on to step 14:
The number 853 fits into 7980 9 times, leaving a remainder of 303.
The number 9 becomes the next digit in our result. 
Result so far: 101837.934349
Deduct 7677 from 7980 and we're left with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Let's proceed to step 15:
The number 853 fits into 3030 3 times, leaving a remainder of 471.
Use 3 as the next digit of our solution. 
Result so far: 101837.9343493
Subtracting 2559 from 3030 leaves us with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

On to step 16:
The number 853 fits into 4710 5 times, leaving a remainder of 445.
The next digit of our result is 5. 
Result so far: 101837.93434935
If we subtract 4265 from 4710, we get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

In conclusion, the division gives 101837.93434935 with a balance of 4.45e-07.
