810776 divided by 420 
Our goal is to divide 810776 by 420.

Step 1:
420 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 420

Going ahead to step 2:
420 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Include the next digit (0) from the dividend after 81, then repeat: 810 / 420

Step 3:
When dividing 810 by 420, we get 1 with a remainder of 390.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 390 after subtracting 420 from 810.
Take the next digit (7) from the dividend and append it to 390, then repeat: 3907 / 420

Step 4:
3907 divided by 420 is 9 with a remainder of 127.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 3780 from 3907 leaves us with 127.
Bring next digit (7) of the dividend behind the 127 and repeat the process: 1277 / 420

Let's proceed to step 5:
If we divide 1277 by 420, we get 3 and a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 193.0
If we take 1260 away from 1277, we end up with 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 420

On to step 6:
When dividing 176 by 420, we get 0 with a remainder of 176.
The number 0 becomes the next digit in our result. 
Result so far: 1930.0
If we subtract 0 from 176, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 7:
When dividing 1760 by 420, we get 4 with a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 1930.4
If we take 1680 away from 1760, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 8:
420 goes into 800 1 times with a remainder of 380.
The number 1 becomes the next digit in our result. 
Result so far: 1930.41
Deduct 420 from 800 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 9:
When dividing 3800 by 420, we get 9 with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 1930.419
If we take 3780 away from 3800, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
420 can be fit into 200 0 times, resulting in a remainder of 200.
The next digit of our result is 0. 
Result so far: 1930.419
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 11:
2000 divided by 420 is 4 with a remainder of 320.
Put 4 as the next digit of the answer. 
Result so far: 1930.41904
If we take 1680 away from 2000, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 12:
When dividing 3200 by 420, we get 7 with a remainder of 260.
Put 7 as the next digit of the answer. 
Result so far: 1930.419047
Subtracting 2940 from 3200 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 13:
2600 divided by 420 is 6 with a remainder of 80.
The next digit of our result is 6. 
Result so far: 1930.4190476
The remainder is 80 after subtracting 2520 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
When dividing 800 by 420, we get 1 with a remainder of 380.
The number 1 becomes the next digit in our result. 
Result so far: 1930.41904761
Subtract 420 from 800 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final outcome is 1930.41904761, with a leftover of 3.8e-07.
