We look at the division of 85835391 by 257 
Our goal is to divide 85835391 by 257.

On to step 1:
The number 257 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 257

Going ahead to step 2:
85 divided by 257 is 0 with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Append the next digit (8) from the dividend to 85 and continue with: 858 / 257

Step 3:
858 divided by 257 is 3 with a remainder of 87.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 771 from 858, we get 87.
Bring next digit (3) of the dividend behind the 87 and repeat the process: 873 / 257

Going ahead to step 4:
873 divided by 257 is 3 with a remainder of 102.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtracting 771 from 873 leaves us with 102.
Append the next digit (5) from the dividend to 102 and continue with: 1025 / 257

Going ahead to step 5:
The number 257 fits into 1025 3 times, leaving a remainder of 254.
Use 3 as the next digit of our solution. 
Result so far: 333.0
Deduct 771 from 1025 and we're left with 254.
Grab the next digit (3) from the dividend, add it to 254, then carry on: 2543 / 257

Step 6:
257 goes into 2543 9 times with a remainder of 230.
Use 9 as the next digit of our solution. 
Result so far: 3339.0
The remainder is 230 after subtracting 2313 from 2543.
Grab the next digit (9) from the dividend, add it to 230, then carry on: 2309 / 257

Let's proceed to step 7:
2309 divided by 257 is 8 with a remainder of 253.
Put 8 as the next digit of the answer. 
Result so far: 33398.0
Deduct 2056 from 2309 and we're left with 253.
Include the next digit (1) from the dividend after 253, then repeat: 2531 / 257

Let's proceed to step 8:
The number 257 fits into 2531 9 times, leaving a remainder of 218.
The number 9 becomes the next digit in our result. 
Result so far: 333989.0
If we take 2313 away from 2531, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 9:
257 can be fit into 2180 8 times, resulting in a remainder of 124.
Record the quotient 8 as the next digit in the result. 
Result so far: 333989.8
Deduct 2056 from 2180 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 10:
The number 257 fits into 1240 4 times, leaving a remainder of 212.
Put 4 as the next digit of the answer. 
Result so far: 333989.84
Deduct 1028 from 1240 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 11:
The number 257 fits into 2120 8 times, leaving a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 333989.848
The remainder is 64 after subtracting 2056 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
If we divide 640 by 257, we get 2 and a remainder of 126.
Use 2 as the next digit of our solution. 
Result so far: 333989.8482
The remainder is 126 after subtracting 514 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 13:
257 goes into 1260 4 times with a remainder of 232.
Write down 4 as next digit of the result. 
Result so far: 333989.84824
Subtract 1028 from 1260 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 14:
2320 divided by 257 is 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 333989.848249
If we take 2313 away from 2320, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 15:
When dividing 70 by 257, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 333989.848249
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 16:
257 can be fit into 700 2 times, resulting in a remainder of 186.
Put 2 as the next digit of the answer. 
Result so far: 333989.84824902
Deduct 514 from 700 and we're left 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.

Our division results in 333989.84824902 with a remaining 1.86e-07.
