We look at the division of 85319131 by 221 
We want to figure out the number of times 85319131 can be divided by 221.

Advancing to step 1:
8 divided by 221 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 221

On to step 2:
221 can be fit into 85 0 times, resulting in a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Include the next digit (3) from the dividend after 85, then repeat: 853 / 221

Let's proceed to step 3:
When dividing 853 by 221, we get 3 with a remainder of 190.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 190 after subtracting 663 from 853.
Take the next digit (1) from the dividend and append it to 190, then repeat: 1901 / 221

Let's proceed to step 4:
The number 221 fits into 1901 8 times, leaving a remainder of 133.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtract 1768 from 1901 to get 133.
Append the next digit (9) from the dividend to 133 and continue with: 1339 / 221

On to step 5:
221 goes into 1339 6 times with a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 386.0
Subtracting 1326 from 1339 leaves us with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 221

Moving on to step 6:
The number 221 fits into 131 0 times, leaving a remainder of 131.
Record the quotient 0 as the next digit in the result. 
Result so far: 3860.0
If we take 0 away from 131, we end up with 131.
Include the next digit (3) from the dividend after 131, then repeat: 1313 / 221

Moving on to step 7:
221 goes into 1313 5 times with a remainder of 208.
The number 5 becomes the next digit in our result. 
Result so far: 38605.0
Subtract 1105 from 1313 to get 208.
Grab the next digit (1) from the dividend, add it to 208, then carry on: 2081 / 221

Let's proceed to step 8:
2081 divided by 221 is 9 with a remainder of 92.
Write down 9 as next digit of the result. 
Result so far: 386059.0
The remainder is 92 after subtracting 1989 from 2081.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 9:
The number 221 fits into 920 4 times, leaving a remainder of 36.
The next digit of our result is 4. 
Result so far: 386059.4
Subtract 884 from 920 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
When dividing 360 by 221, we get 1 with a remainder of 139.
Write down 1 as next digit of the result. 
Result so far: 386059.41
The remainder is 139 after subtracting 221 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Moving on to step 11:
When dividing 1390 by 221, we get 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 386059.416
If we subtract 1326 from 1390, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
When dividing 640 by 221, we get 2 with a remainder of 198.
The number 2 becomes the next digit in our result. 
Result so far: 386059.4162
Subtract 442 from 640 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 13:
221 goes into 1980 8 times with a remainder of 212.
Write down 8 as next digit of the result. 
Result so far: 386059.41628
Subtracting 1768 from 1980 leaves us 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.

Step 14:
221 can be fit into 2120 9 times, resulting in a remainder of 131.
Put 9 as the next digit of the answer. 
Result so far: 386059.416289
If we subtract 1989 from 2120, we get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Moving on to step 15:
221 can be fit into 1310 5 times, resulting in a remainder of 205.
Use 5 as the next digit of our solution. 
Result so far: 386059.4162895
The remainder is 205 after subtracting 1105 from 1310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 16:
The number 221 fits into 2050 9 times, leaving a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 386059.41628959
Subtract 1989 from 2050 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The final outcome is 386059.41628959, with a leftover of 6.1e-08.
