Let's divide 85712572 by 402
Let's see how many times 402 fits into 85712572.

Step 1:
The number 402 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 402

Let's proceed to step 2:
402 goes into 85 0 times with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Bring next digit (7) of the dividend behind the 85 and repeat the process: 857 / 402

Step 3:
The number 402 fits into 857 2 times, leaving a remainder of 53.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 804 from 857 to get 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 402

Moving on to step 4:
402 can be fit into 531 1 times, resulting in a remainder of 129.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 129 after subtracting 402 from 531.
Bring next digit (2) of the dividend behind the 129 and repeat the process: 1292 / 402

Let's proceed to step 5:
The number 402 fits into 1292 3 times, leaving a remainder of 86.
Use 3 as the next digit of our solution. 
Result so far: 213.0
Subtract 1206 from 1292 to get 86.
Bring next digit (5) of the dividend behind the 86 and repeat the process: 865 / 402

Step 6:
865 divided by 402 is 2 with a remainder of 61.
The next digit of our result is 2. 
Result so far: 2132.0
Deduct 804 from 865 and we're left with 61.
Append the next digit (7) from the dividend to 61 and continue with: 617 / 402

Let's proceed to step 7:
The number 402 fits into 617 1 times, leaving a remainder of 215.
Record the quotient 1 as the next digit in the result. 
Result so far: 21321.0
If we subtract 402 from 617, we get 215.
Take the next digit (2) from the dividend and append it to 215, then repeat: 2152 / 402

Going ahead to step 8:
402 can be fit into 2152 5 times, resulting in a remainder of 142.
Record the quotient 5 as the next digit in the result. 
Result so far: 213215.0
Subtract 2010 from 2152 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Going ahead to step 9:
The number 402 fits into 1420 3 times, leaving a remainder of 214.
The number 3 becomes the next digit in our result. 
Result so far: 213215.3
Deduct 1206 from 1420 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Going ahead to step 10:
If we divide 2140 by 402, we get 5 and a remainder of 130.
Put 5 as the next digit of the answer. 
Result so far: 213215.35
Subtracting 2010 from 2140 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 11:
402 goes into 1300 3 times with a remainder of 94.
Write down 3 as next digit of the result. 
Result so far: 213215.353
Subtract 1206 from 1300 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 12:
If we divide 940 by 402, we get 2 and a remainder of 136.
The number 2 becomes the next digit in our result. 
Result so far: 213215.3532
If we subtract 804 from 940, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 13:
402 can be fit into 1360 3 times, resulting in a remainder of 154.
Put 3 as the next digit of the answer. 
Result so far: 213215.35323
The remainder is 154 after subtracting 1206 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Let's proceed to step 14:
If we divide 1540 by 402, we get 3 and a remainder of 334.
The next digit of our result is 3. 
Result so far: 213215.353233
If we subtract 1206 from 1540, we get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

The final result is 213215.353233 with a remainder of 3.34e-05.
