We're dividing 85428743 by 355 
Our goal is to divide 85428743 by 355.

Step 1:
355 can be fit into 8 0 times, resulting in 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.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 355

On to step 2:
When dividing 85 by 355, we get 0 with a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Fetch the next digit (4) from the dividend, attach it to 85 and continue: 854 / 355

Step 3:
When dividing 854 by 355, we get 2 with a remainder of 144.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 710 from 854 and we're left with 144.
Grab the next digit (2) from the dividend, add it to 144, then carry on: 1442 / 355

On to step 4:
1442 divided by 355 is 4 with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
The remainder is 22 after subtracting 1420 from 1442.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 355

Step 5:
355 can be fit into 228 0 times, resulting in a remainder of 228.
Put 0 as the next digit of the answer. 
Result so far: 240.0
Subtract 0 from 228 to get 228.
Bring next digit (7) of the dividend behind the 228 and repeat the process: 2287 / 355

Going ahead to step 6:
355 can be fit into 2287 6 times, resulting in a remainder of 157.
The number 6 becomes the next digit in our result. 
Result so far: 2406.0
Subtract 2130 from 2287 to get 157.
Take the next digit (4) from the dividend and append it to 157, then repeat: 1574 / 355

Step 7:
355 goes into 1574 4 times with a remainder of 154.
The next digit of our result is 4. 
Result so far: 24064.0
If we take 1420 away from 1574, we end up with 154.
Grab the next digit (3) from the dividend, add it to 154, then carry on: 1543 / 355

Moving on to step 8:
When dividing 1543 by 355, we get 4 with a remainder of 123.
Record the quotient 4 as the next digit in the result. 
Result so far: 240644.0
Subtracting 1420 from 1543 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 9:
If we divide 1230 by 355, we get 3 and a remainder of 165.
The number 3 becomes the next digit in our result. 
Result so far: 240644.3
Subtracting 1065 from 1230 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 10:
The number 355 fits into 1650 4 times, leaving a remainder of 230.
Put 4 as the next digit of the answer. 
Result so far: 240644.34
If we subtract 1420 from 1650, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 11:
355 goes into 2300 6 times with a remainder of 170.
The number 6 becomes the next digit in our result. 
Result so far: 240644.346
If we subtract 2130 from 2300, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 12:
355 goes into 1700 4 times with a remainder of 280.
The next digit of our result is 4. 
Result so far: 240644.3464
Subtract 1420 from 1700 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 13:
When dividing 2800 by 355, we get 7 with a remainder of 315.
Put 7 as the next digit of the answer. 
Result so far: 240644.34647
Subtracting 2485 from 2800 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 14:
355 can be fit into 3150 8 times, resulting in a remainder of 310.
Record the quotient 8 as the next digit in the result. 
Result so far: 240644.346478
The remainder is 310 after subtracting 2840 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 15:
355 can be fit into 3100 8 times, resulting in a remainder of 260.
Record the quotient 8 as the next digit in the result. 
Result so far: 240644.3464788
Subtracting 2840 from 3100 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

After the division, we end up with 240644.3464788 and a remainder of 2.6e-06.
