We're dividing 86432903 by 849 
We want to divide 86432903 by 849.

Advancing to step 1:
The number 849 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 849

Advancing to step 2:
849 can be fit into 86 0 times, resulting in a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Append the next digit (4) from the dividend to 86 and continue with: 864 / 849

Moving on to step 3:
849 goes into 864 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 849 from 864, we get 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 849

Let's proceed to step 4:
The number 849 fits into 153 0 times, leaving a remainder of 153.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 153 leaves us with 153.
Include the next digit (2) from the dividend after 153, then repeat: 1532 / 849

Step 5:
When dividing 1532 by 849, we get 1 with a remainder of 683.
Put 1 as the next digit of the answer. 
Result so far: 101.0
If we take 849 away from 1532, we end up with 683.
Bring next digit (9) of the dividend behind the 683 and repeat the process: 6839 / 849

Step 6:
849 goes into 6839 8 times with a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 1018.0
Deduct 6792 from 6839 and we're left with 47.
Take the next digit (0) from the dividend and append it to 47, then repeat: 470 / 849

Moving on to step 7:
849 can be fit into 470 0 times, resulting in a remainder of 470.
The number 0 becomes the next digit in our result. 
Result so far: 10180.0
Subtracting 0 from 470 leaves us with 470.
Bring next digit (3) of the dividend behind the 470 and repeat the process: 4703 / 849

Let's proceed to step 8:
4703 divided by 849 is 5 with a remainder of 458.
Put 5 as the next digit of the answer. 
Result so far: 101805.0
If we take 4245 away from 4703, we end up with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

On to step 9:
If we divide 4580 by 849, we get 5 and a remainder of 335.
The number 5 becomes the next digit in our result. 
Result so far: 101805.5
If we subtract 4245 from 4580, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 10:
When dividing 3350 by 849, we get 3 with a remainder of 803.
Use 3 as the next digit of our solution. 
Result so far: 101805.53
Subtract 2547 from 3350 to get 803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8030, and continue the process.

On to step 11:
8030 divided by 849 is 9 with a remainder of 389.
Use 9 as the next digit of our solution. 
Result so far: 101805.539
Deduct 7641 from 8030 and we're left with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Moving on to step 12:
If we divide 3890 by 849, we get 4 and a remainder of 494.
Write down 4 as next digit of the result. 
Result so far: 101805.5394
Subtracting 3396 from 3890 leaves us with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

On to step 13:
849 goes into 4940 5 times with a remainder of 695.
Put 5 as the next digit of the answer. 
Result so far: 101805.53945
Deduct 4245 from 4940 and we're left with 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

On to step 14:
849 can be fit into 6950 8 times, resulting in a remainder of 158.
The number 8 becomes the next digit in our result. 
Result so far: 101805.539458
If we subtract 6792 from 6950, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 15:
When dividing 1580 by 849, we get 1 with a remainder of 731.
Record the quotient 1 as the next digit in the result. 
Result so far: 101805.5394581
Subtracting 849 from 1580 leaves us with 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

Advancing to step 16:
When dividing 7310 by 849, we get 8 with a remainder of 518.
Use 8 as the next digit of our solution. 
Result so far: 101805.53945818
If we subtract 6792 from 7310, we get 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

In conclusion, the division gives 101805.53945818 with a balance of 5.18e-07.
