Let's divide 1551812 by 805
We want to figure out the number of times 1551812 can be divided by 805.

On to step 1:
1 divided by 805 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 805

On to step 2:
If we divide 15 by 805, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 805

Advancing to step 3:
805 can be fit into 155 0 times, resulting in a remainder of 155.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 155 and we're left with 155.
Append the next digit (1) from the dividend to 155 and continue with: 1551 / 805

Step 4:
When dividing 1551 by 805, we get 1 with a remainder of 746.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 805 from 1551 and we're left with 746.
Append the next digit (8) from the dividend to 746 and continue with: 7468 / 805

Moving on to step 5:
805 can be fit into 7468 9 times, resulting in a remainder of 223.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 7245 from 7468 to get 223.
Include the next digit (1) from the dividend after 223, then repeat: 2231 / 805

Going ahead to step 6:
If we divide 2231 by 805, we get 2 and a remainder of 621.
Write down 2 as next digit of the result. 
Result so far: 192.0
If we take 1610 away from 2231, we end up with 621.
Take the next digit (2) from the dividend and append it to 621, then repeat: 6212 / 805

Advancing to step 7:
805 goes into 6212 7 times with a remainder of 577.
Put 7 as the next digit of the answer. 
Result so far: 1927.0
If we subtract 5635 from 6212, we get 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Advancing to step 8:
805 can be fit into 5770 7 times, resulting in a remainder of 135.
Write down 7 as next digit of the result. 
Result so far: 1927.7
Subtract 5635 from 5770 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 9:
The number 805 fits into 1350 1 times, leaving a remainder of 545.
Record the quotient 1 as the next digit in the result. 
Result so far: 1927.71
Subtracting 805 from 1350 leaves us with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

On to step 10:
805 goes into 5450 6 times with a remainder of 620.
Record the quotient 6 as the next digit in the result. 
Result so far: 1927.716
Subtract 4830 from 5450 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 11:
If we divide 6200 by 805, we get 7 and a remainder of 565.
The next digit of our result is 7. 
Result so far: 1927.7167
If we subtract 5635 from 6200, we get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Step 12:
The number 805 fits into 5650 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 1927.71677
Deduct 5635 from 5650 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 1927.71677 with a balance of 1.5e-05.
