We look at the division of 83789841 by 809 
We want to figure out the number of times 83789841 can be divided by 809.

Let's proceed to step 1:
809 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 809

Step 2:
83 divided by 809 is 0 with a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Bring next digit (7) of the dividend behind the 83 and repeat the process: 837 / 809

On to step 3:
The number 809 fits into 837 1 times, leaving a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 809 from 837, we get 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 809

Advancing to step 4:
809 goes into 288 0 times with a remainder of 288.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 288 to get 288.
Grab the next digit (9) from the dividend, add it to 288, then carry on: 2889 / 809

On to step 5:
809 can be fit into 2889 3 times, resulting in a remainder of 462.
Put 3 as the next digit of the answer. 
Result so far: 103.0
Subtracting 2427 from 2889 leaves us with 462.
Append the next digit (8) from the dividend to 462 and continue with: 4628 / 809

Going ahead to step 6:
809 goes into 4628 5 times with a remainder of 583.
Put 5 as the next digit of the answer. 
Result so far: 1035.0
Deduct 4045 from 4628 and we're left with 583.
Fetch the next digit (4) from the dividend, attach it to 583 and continue: 5834 / 809

Let's proceed to step 7:
The number 809 fits into 5834 7 times, leaving a remainder of 171.
Use 7 as the next digit of our solution. 
Result so far: 10357.0
Subtracting 5663 from 5834 leaves us with 171.
Include the next digit (1) from the dividend after 171, then repeat: 1711 / 809

Advancing to step 8:
809 goes into 1711 2 times with a remainder of 93.
Use 2 as the next digit of our solution. 
Result so far: 103572.0
If we take 1618 away from 1711, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 9:
809 can be fit into 930 1 times, resulting in a remainder of 121.
Use 1 as the next digit of our solution. 
Result so far: 103572.1
If we subtract 809 from 930, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 10:
The number 809 fits into 1210 1 times, leaving a remainder of 401.
Put 1 as the next digit of the answer. 
Result so far: 103572.11
If we subtract 809 from 1210, we get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Our division results in 103572.11 with a remaining 0.401.
