Let's divide 85109053 by 424
Our goal is to divide 85109053 by 424.

Going ahead to step 1:
If we divide 8 by 424, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 424

Advancing to step 2:
424 goes into 85 0 times with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Include the next digit (1) from the dividend after 85, then repeat: 851 / 424

On to step 3:
851 divided by 424 is 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 848 from 851 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 424

Going ahead to step 4:
If we divide 30 by 424, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 424

Going ahead to step 5:
424 can be fit into 309 0 times, resulting in a remainder of 309.
Use 0 as the next digit of our solution. 
Result so far: 200.0
If we subtract 0 from 309, we get 309.
Take the next digit (0) from the dividend and append it to 309, then repeat: 3090 / 424

Going ahead to step 6:
If we divide 3090 by 424, we get 7 and a remainder of 122.
Record the quotient 7 as the next digit in the result. 
Result so far: 2007.0
The remainder is 122 after subtracting 2968 from 3090.
Bring next digit (5) of the dividend behind the 122 and repeat the process: 1225 / 424

Let's proceed to step 7:
The number 424 fits into 1225 2 times, leaving a remainder of 377.
The number 2 becomes the next digit in our result. 
Result so far: 20072.0
Subtracting 848 from 1225 leaves us with 377.
Grab the next digit (3) from the dividend, add it to 377, then carry on: 3773 / 424

Let's proceed to step 8:
424 can be fit into 3773 8 times, resulting in a remainder of 381.
Record the quotient 8 as the next digit in the result. 
Result so far: 200728.0
If we take 3392 away from 3773, we end up with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Let's proceed to step 9:
If we divide 3810 by 424, we get 8 and a remainder of 418.
Record the quotient 8 as the next digit in the result. 
Result so far: 200728.8
If we take 3392 away from 3810, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Let's proceed to step 10:
424 goes into 4180 9 times with a remainder of 364.
The next digit of our result is 9. 
Result so far: 200728.89
Subtracting 3816 from 4180 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 11:
The number 424 fits into 3640 8 times, leaving a remainder of 248.
The next digit of our result is 8. 
Result so far: 200728.898
Subtract 3392 from 3640 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 12:
2480 divided by 424 is 5 with a remainder of 360.
Put 5 as the next digit of the answer. 
Result so far: 200728.8985
If we subtract 2120 from 2480, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 13:
The number 424 fits into 3600 8 times, leaving a remainder of 208.
Use 8 as the next digit of our solution. 
Result so far: 200728.89858
Deduct 3392 from 3600 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 14:
When dividing 2080 by 424, we get 4 with a remainder of 384.
The next digit of our result is 4. 
Result so far: 200728.898584
Subtracting 1696 from 2080 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 15:
424 can be fit into 3840 9 times, resulting in a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 200728.8985849
Subtract 3816 from 3840 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 16:
424 goes into 240 0 times with a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 200728.8985849
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 200728.8985849 with a remainder of 2.4e-07.
