85031992 ÷ 815 
Our goal is to divide 85031992 by 815.

Going ahead to step 1:
815 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 815

Let's proceed to step 2:
815 goes into 85 0 times with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Include the next digit (0) from the dividend after 85, then repeat: 850 / 815

Step 3:
When dividing 850 by 815, we get 1 with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 815 from 850 leaves us with 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 815

Going ahead to step 4:
The number 815 fits into 353 0 times, leaving a remainder of 353.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 353 to get 353.
Append the next digit (1) from the dividend to 353 and continue with: 3531 / 815

Going ahead to step 5:
When dividing 3531 by 815, we get 4 with a remainder of 271.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
If we take 3260 away from 3531, we end up with 271.
Append the next digit (9) from the dividend to 271 and continue with: 2719 / 815

Advancing to step 6:
If we divide 2719 by 815, we get 3 and a remainder of 274.
The number 3 becomes the next digit in our result. 
Result so far: 1043.0
Subtracting 2445 from 2719 leaves us with 274.
Fetch the next digit (9) from the dividend, attach it to 274 and continue: 2749 / 815

Let's proceed to step 7:
When dividing 2749 by 815, we get 3 with a remainder of 304.
Put 3 as the next digit of the answer. 
Result so far: 10433.0
If we subtract 2445 from 2749, we get 304.
Append the next digit (2) from the dividend to 304 and continue with: 3042 / 815

Step 8:
815 can be fit into 3042 3 times, resulting in a remainder of 597.
The next digit of our result is 3. 
Result so far: 104333.0
Deduct 2445 from 3042 and we're left with 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Going ahead to step 9:
If we divide 5970 by 815, we get 7 and a remainder of 265.
The next digit of our result is 7. 
Result so far: 104333.7
Subtracting 5705 from 5970 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 10:
If we divide 2650 by 815, we get 3 and a remainder of 205.
Write down 3 as next digit of the result. 
Result so far: 104333.73
If we take 2445 away from 2650, we end up with 205.
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 11:
The number 815 fits into 2050 2 times, leaving a remainder of 420.
The number 2 becomes the next digit in our result. 
Result so far: 104333.732
If we take 1630 away from 2050, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 12:
When dividing 4200 by 815, we get 5 with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 104333.7325
Subtracting 4075 from 4200 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 13:
815 can be fit into 1250 1 times, resulting in a remainder of 435.
The next digit of our result is 1. 
Result so far: 104333.73251
If we subtract 815 from 1250, we get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Let's proceed to step 14:
When dividing 4350 by 815, we get 5 with a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 104333.732515
Deduct 4075 from 4350 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 15:
If we divide 2750 by 815, we get 3 and a remainder of 305.
Put 3 as the next digit of the answer. 
Result so far: 104333.7325153
Deduct 2445 from 2750 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 16:
815 can be fit into 3050 3 times, resulting in a remainder of 605.
Put 3 as the next digit of the answer. 
Result so far: 104333.73251533
Deduct 2445 from 3050 and we're left with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

The final result is 104333.73251533 with a remainder of 6.05e-07.
