42097749 divided by 820 
Our goal is to divide 42097749 by 820.

On to step 1:
4 divided by 820 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 820

Let's proceed to step 2:
42 divided by 820 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 820

Moving on to step 3:
When dividing 420 by 820, we get 0 with a remainder of 420.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 420, we get 420.
Take the next digit (9) from the dividend and append it to 420, then repeat: 4209 / 820

Moving on to step 4:
820 can be fit into 4209 5 times, resulting in a remainder of 109.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 4100 from 4209 leaves us with 109.
Fetch the next digit (7) from the dividend, attach it to 109 and continue: 1097 / 820

Going ahead to step 5:
The number 820 fits into 1097 1 times, leaving a remainder of 277.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we subtract 820 from 1097, we get 277.
Grab the next digit (7) from the dividend, add it to 277, then carry on: 2777 / 820

Let's proceed to step 6:
The number 820 fits into 2777 3 times, leaving a remainder of 317.
Record the quotient 3 as the next digit in the result. 
Result so far: 513.0
If we subtract 2460 from 2777, we get 317.
Grab the next digit (4) from the dividend, add it to 317, then carry on: 3174 / 820

Let's proceed to step 7:
If we divide 3174 by 820, we get 3 and a remainder of 714.
Put 3 as the next digit of the answer. 
Result so far: 5133.0
Subtracting 2460 from 3174 leaves us with 714.
Fetch the next digit (9) from the dividend, attach it to 714 and continue: 7149 / 820

Step 8:
820 goes into 7149 8 times with a remainder of 589.
The number 8 becomes the next digit in our result. 
Result so far: 51338.0
Subtracting 6560 from 7149 leaves us with 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Advancing to step 9:
When dividing 5890 by 820, we get 7 with a remainder of 150.
Record the quotient 7 as the next digit in the result. 
Result so far: 51338.7
Deduct 5740 from 5890 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 10:
820 can be fit into 1500 1 times, resulting in a remainder of 680.
Put 1 as the next digit of the answer. 
Result so far: 51338.71
Subtract 820 from 1500 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 11:
820 can be fit into 6800 8 times, resulting in a remainder of 240.
Record the quotient 8 as the next digit in the result. 
Result so far: 51338.718
Deduct 6560 from 6800 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
If we divide 2400 by 820, we get 2 and a remainder of 760.
Put 2 as the next digit of the answer. 
Result so far: 51338.7182
The remainder is 760 after subtracting 1640 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Moving on to step 13:
820 goes into 7600 9 times with a remainder of 220.
The number 9 becomes the next digit in our result. 
Result so far: 51338.71829
If we take 7380 away from 7600, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 14:
2200 divided by 820 is 2 with a remainder of 560.
Record the quotient 2 as the next digit in the result. 
Result so far: 51338.718292
If we subtract 1640 from 2200, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 15:
5600 divided by 820 is 6 with a remainder of 680.
Use 6 as the next digit of our solution. 
Result so far: 51338.7182926
Deduct 4920 from 5600 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 16:
6800 divided by 820 is 8 with a remainder of 240.
Record the quotient 8 as the next digit in the result. 
Result so far: 51338.71829268
If we subtract 6560 from 6800, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

After the division, we end up with 51338.71829268 and a remainder of 2.4e-07.
