Let's divide 85808003 by 839
We want to divide 85808003 by 839.

On to step 1:
When dividing 8 by 839, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 839

Moving on to step 2:
839 can be fit into 85 0 times, resulting in a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Include the next digit (8) from the dividend after 85, then repeat: 858 / 839

Moving on to step 3:
When dividing 858 by 839, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 839 from 858 to get 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 839

Going ahead to step 4:
839 goes into 190 0 times with a remainder of 190.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 190 and we're left with 190.
Include the next digit (8) from the dividend after 190, then repeat: 1908 / 839

Let's proceed to step 5:
When dividing 1908 by 839, we get 2 with a remainder of 230.
The next digit of our result is 2. 
Result so far: 102.0
If we subtract 1678 from 1908, we get 230.
Fetch the next digit (0) from the dividend, attach it to 230 and continue: 2300 / 839

On to step 6:
839 goes into 2300 2 times with a remainder of 622.
Record the quotient 2 as the next digit in the result. 
Result so far: 1022.0
Deduct 1678 from 2300 and we're left with 622.
Bring next digit (0) of the dividend behind the 622 and repeat the process: 6220 / 839

Advancing to step 7:
839 can be fit into 6220 7 times, resulting in a remainder of 347.
Put 7 as the next digit of the answer. 
Result so far: 10227.0
If we subtract 5873 from 6220, we get 347.
Grab the next digit (3) from the dividend, add it to 347, then carry on: 3473 / 839

Moving on to step 8:
If we divide 3473 by 839, we get 4 and a remainder of 117.
Put 4 as the next digit of the answer. 
Result so far: 102274.0
Subtract 3356 from 3473 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Advancing to step 9:
1170 divided by 839 is 1 with a remainder of 331.
The next digit of our result is 1. 
Result so far: 102274.1
Deduct 839 from 1170 and we're left with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Going ahead to step 10:
839 goes into 3310 3 times with a remainder of 793.
Write down 3 as next digit of the result. 
Result so far: 102274.13
If we subtract 2517 from 3310, we get 793.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

Advancing to step 11:
839 goes into 7930 9 times with a remainder of 379.
Put 9 as the next digit of the answer. 
Result so far: 102274.139
Deduct 7551 from 7930 and we're left with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

On to step 12:
839 goes into 3790 4 times with a remainder of 434.
The number 4 becomes the next digit in our result. 
Result so far: 102274.1394
The remainder is 434 after subtracting 3356 from 3790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Step 13:
When dividing 4340 by 839, we get 5 with a remainder of 145.
Put 5 as the next digit of the answer. 
Result so far: 102274.13945
The remainder is 145 after subtracting 4195 from 4340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 14:
If we divide 1450 by 839, we get 1 and a remainder of 611.
The number 1 becomes the next digit in our result. 
Result so far: 102274.139451
Deduct 839 from 1450 and we're left with 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Going ahead to step 15:
839 goes into 6110 7 times with a remainder of 237.
Write down 7 as next digit of the result. 
Result so far: 102274.1394517
The remainder is 237 after subtracting 5873 from 6110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Advancing to step 16:
When dividing 2370 by 839, we get 2 with a remainder of 692.
Put 2 as the next digit of the answer. 
Result so far: 102274.13945172
If we take 1678 away from 2370, we end up with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

The final result is 102274.13945172 with a remainder of 6.92e-07.
