We look at the division of 85458336 by 571 
We want to divide 85458336 by 571.

On to step 1:
When dividing 8 by 571, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 571

Advancing to step 2:
571 can be fit into 85 0 times, resulting in 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.
Bring next digit (4) of the dividend behind the 85 and repeat the process: 854 / 571

Advancing to step 3:
571 goes into 854 1 times with a remainder of 283.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 283 after subtracting 571 from 854.
Grab the next digit (5) from the dividend, add it to 283, then carry on: 2835 / 571

Moving on to step 4:
2835 divided by 571 is 4 with a remainder of 551.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 2284 from 2835 and we're left with 551.
Append the next digit (8) from the dividend to 551 and continue with: 5518 / 571

Going ahead to step 5:
571 can be fit into 5518 9 times, resulting in a remainder of 379.
Record the quotient 9 as the next digit in the result. 
Result so far: 149.0
Subtract 5139 from 5518 to get 379.
Append the next digit (3) from the dividend to 379 and continue with: 3793 / 571

Step 6:
If we divide 3793 by 571, we get 6 and a remainder of 367.
Write down 6 as next digit of the result. 
Result so far: 1496.0
If we take 3426 away from 3793, we end up with 367.
Bring next digit (3) of the dividend behind the 367 and repeat the process: 3673 / 571

Moving on to step 7:
571 can be fit into 3673 6 times, resulting in a remainder of 247.
Use 6 as the next digit of our solution. 
Result so far: 14966.0
If we take 3426 away from 3673, we end up with 247.
Append the next digit (6) from the dividend to 247 and continue with: 2476 / 571

Step 8:
571 goes into 2476 4 times with a remainder of 192.
Use 4 as the next digit of our solution. 
Result so far: 149664.0
The remainder is 192 after subtracting 2284 from 2476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 9:
The number 571 fits into 1920 3 times, leaving a remainder of 207.
Put 3 as the next digit of the answer. 
Result so far: 149664.3
Deduct 1713 from 1920 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Let's proceed to step 10:
The number 571 fits into 2070 3 times, leaving a remainder of 357.
Write down 3 as next digit of the result. 
Result so far: 149664.33
Subtract 1713 from 2070 to get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

The quotient of the division is 149664.33, and the remainder is 0.357.
