We look at the division of 65590843 by 83 
We want to divide 65590843 by 83.

Advancing to step 1:
When dividing 6 by 83, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 83

Advancing to step 2:
If we divide 65 by 83, we get 0 and a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Fetch the next digit (5) from the dividend, attach it to 65 and continue: 655 / 83

On to step 3:
When dividing 655 by 83, we get 7 with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 581 from 655 and we're left with 74.
Include the next digit (9) from the dividend after 74, then repeat: 749 / 83

On to step 4:
749 divided by 83 is 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
The remainder is 2 after subtracting 747 from 749.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 83

Let's proceed to step 5:
83 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 790.0
Subtract 0 from 20 to get 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 83

Step 6:
208 divided by 83 is 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 7902.0
The remainder is 42 after subtracting 166 from 208.
Grab the next digit (4) from the dividend, add it to 42, then carry on: 424 / 83

On to step 7:
83 goes into 424 5 times with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 79025.0
If we subtract 415 from 424, we get 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 83

On to step 8:
93 divided by 83 is 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 790251.0
Subtract 83 from 93 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
If we divide 100 by 83, we get 1 and a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 790251.1
If we subtract 83 from 100, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
83 can be fit into 170 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 790251.12
If we take 166 away from 170, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
40 divided by 83 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 790251.12
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
The number 83 fits into 400 4 times, leaving a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 790251.1204
If we subtract 332 from 400, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
When dividing 680 by 83, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 790251.12048
Subtract 664 from 680 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
When dividing 160 by 83, we get 1 with a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 790251.120481
Deduct 83 from 160 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 15:
83 can be fit into 770 9 times, resulting in a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 790251.1204819
If we take 747 away from 770, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 16:
The number 83 fits into 230 2 times, leaving a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 790251.12048192
If we take 166 away from 230, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 790251.12048192 with a remainder of 6.4e-08.
