We look at the division of 85782601 by 31 
Our goal is to divide 85782601 by 31.

On to step 1:
31 can be fit into 8 0 times, resulting in 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.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 31

Moving on to step 2:
85 divided by 31 is 2 with a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 62 from 85 leaves us with 23.
Grab the next digit (7) from the dividend, add it to 23, then carry on: 237 / 31

Going ahead to step 3:
237 divided by 31 is 7 with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we take 217 away from 237, we end up with 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 31

On to step 4:
When dividing 208 by 31, we get 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 276.0
Subtracting 186 from 208 leaves us with 22.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 31

Advancing to step 5:
If we divide 222 by 31, we get 7 and a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 2767.0
Subtract 217 from 222 to get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 31

Step 6:
The number 31 fits into 56 1 times, leaving a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 27671.0
The remainder is 25 after subtracting 31 from 56.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 31

Let's proceed to step 7:
31 goes into 250 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 276718.0
Deduct 248 from 250 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 31

Step 8:
31 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 2767180.0
If we take 0 away from 21, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
When dividing 210 by 31, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 2767180.6
The remainder is 24 after subtracting 186 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
31 can be fit into 240 7 times, resulting in a remainder of 23.
The next digit of our result is 7. 
Result so far: 2767180.67
Subtracting 217 from 240 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 11:
When dividing 230 by 31, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 2767180.677
Subtract 217 from 230 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 2767180.677, and the remainder is 0.0013.
