90819045 ÷ 806 
Our goal is to divide 90819045 by 806.

On to step 1:
806 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 806

Step 2:
806 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Take the next digit (8) from the dividend and append it to 90, then repeat: 908 / 806

On to step 3:
The number 806 fits into 908 1 times, leaving a remainder of 102.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 806 from 908 leaves us with 102.
Append the next digit (1) from the dividend to 102 and continue with: 1021 / 806

Moving on to step 4:
If we divide 1021 by 806, we get 1 and a remainder of 215.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 806 from 1021 and we're left with 215.
Fetch the next digit (9) from the dividend, attach it to 215 and continue: 2159 / 806

Advancing to step 5:
If we divide 2159 by 806, we get 2 and a remainder of 547.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Subtract 1612 from 2159 to get 547.
Fetch the next digit (0) from the dividend, attach it to 547 and continue: 5470 / 806

Moving on to step 6:
5470 divided by 806 is 6 with a remainder of 634.
Write down 6 as next digit of the result. 
Result so far: 1126.0
Subtract 4836 from 5470 to get 634.
Include the next digit (4) from the dividend after 634, then repeat: 6344 / 806

On to step 7:
806 can be fit into 6344 7 times, resulting in a remainder of 702.
The number 7 becomes the next digit in our result. 
Result so far: 11267.0
Subtracting 5642 from 6344 leaves us with 702.
Bring next digit (5) of the dividend behind the 702 and repeat the process: 7025 / 806

Going ahead to step 8:
806 goes into 7025 8 times with a remainder of 577.
Record the quotient 8 as the next digit in the result. 
Result so far: 112678.0
If we take 6448 away from 7025, we end up with 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Going ahead to step 9:
806 can be fit into 5770 7 times, resulting in a remainder of 128.
The number 7 becomes the next digit in our result. 
Result so far: 112678.7
The remainder is 128 after subtracting 5642 from 5770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 10:
When dividing 1280 by 806, we get 1 with a remainder of 474.
The next digit of our result is 1. 
Result so far: 112678.71
If we take 806 away from 1280, we end up with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

On to step 11:
If we divide 4740 by 806, we get 5 and a remainder of 710.
Use 5 as the next digit of our solution. 
Result so far: 112678.715
If we subtract 4030 from 4740, we get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Let's proceed to step 12:
806 can be fit into 7100 8 times, resulting in a remainder of 652.
Use 8 as the next digit of our solution. 
Result so far: 112678.7158
If we take 6448 away from 7100, we end up with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Advancing to step 13:
When dividing 6520 by 806, we get 8 with a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 112678.71588
Deduct 6448 from 6520 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 112678.71588 with a remaining 7.2e-05.
