83789443 divided by 809 
Let's see how many times 809 fits into 83789443.

Advancing to step 1:
809 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 809

Moving on to step 2:
83 divided by 809 is 0 with a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Grab the next digit (7) from the dividend, add it to 83, then carry on: 837 / 809

Going ahead to step 3:
809 goes into 837 1 times with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 809 from 837 and we're left with 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 809

Advancing to step 4:
The number 809 fits into 288 0 times, leaving a remainder of 288.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 288 and we're left with 288.
Take the next digit (9) from the dividend and append it to 288, then repeat: 2889 / 809

Let's proceed to step 5:
If we divide 2889 by 809, we get 3 and a remainder of 462.
Put 3 as the next digit of the answer. 
Result so far: 103.0
If we take 2427 away from 2889, we end up with 462.
Fetch the next digit (4) from the dividend, attach it to 462 and continue: 4624 / 809

Going ahead to step 6:
809 can be fit into 4624 5 times, resulting in a remainder of 579.
The number 5 becomes the next digit in our result. 
Result so far: 1035.0
If we subtract 4045 from 4624, we get 579.
Take the next digit (4) from the dividend and append it to 579, then repeat: 5794 / 809

Going ahead to step 7:
809 can be fit into 5794 7 times, resulting in a remainder of 131.
Put 7 as the next digit of the answer. 
Result so far: 10357.0
If we subtract 5663 from 5794, we get 131.
Take the next digit (3) from the dividend and append it to 131, then repeat: 1313 / 809

Advancing to step 8:
1313 divided by 809 is 1 with a remainder of 504.
The next digit of our result is 1. 
Result so far: 103571.0
Subtract 809 from 1313 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Moving on to step 9:
The number 809 fits into 5040 6 times, leaving a remainder of 186.
Put 6 as the next digit of the answer. 
Result so far: 103571.6
Subtracting 4854 from 5040 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 10:
The number 809 fits into 1860 2 times, leaving a remainder of 242.
Record the quotient 2 as the next digit in the result. 
Result so far: 103571.62
Deduct 1618 from 1860 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 11:
If we divide 2420 by 809, we get 2 and a remainder of 802.
The number 2 becomes the next digit in our result. 
Result so far: 103571.622
If we subtract 1618 from 2420, we get 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

In conclusion, the division gives 103571.622 with a balance of 0.0802.
