Let's divide 30677871 by 820
Our goal is to divide 30677871 by 820.

Step 1:
820 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 820

Going ahead to step 2:
820 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 820

Advancing to step 3:
820 goes into 306 0 times with a remainder of 306.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 306, we get 306.
Fetch the next digit (7) from the dividend, attach it to 306 and continue: 3067 / 820

Moving on to step 4:
820 goes into 3067 3 times with a remainder of 607.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 2460 from 3067, we get 607.
Take the next digit (7) from the dividend and append it to 607, then repeat: 6077 / 820

Step 5:
When dividing 6077 by 820, we get 7 with a remainder of 337.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Deduct 5740 from 6077 and we're left with 337.
Grab the next digit (8) from the dividend, add it to 337, then carry on: 3378 / 820

Going ahead to step 6:
3378 divided by 820 is 4 with a remainder of 98.
The number 4 becomes the next digit in our result. 
Result so far: 374.0
Subtract 3280 from 3378 to get 98.
Grab the next digit (7) from the dividend, add it to 98, then carry on: 987 / 820

Step 7:
820 goes into 987 1 times with a remainder of 167.
Record the quotient 1 as the next digit in the result. 
Result so far: 3741.0
The remainder is 167 after subtracting 820 from 987.
Take the next digit (1) from the dividend and append it to 167, then repeat: 1671 / 820

On to step 8:
1671 divided by 820 is 2 with a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 37412.0
Subtract 1640 from 1671 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
820 can be fit into 310 0 times, resulting in a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 37412.0
If we subtract 0 from 310, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 10:
820 goes into 3100 3 times with a remainder of 640.
The number 3 becomes the next digit in our result. 
Result so far: 37412.03
Deduct 2460 from 3100 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 11:
The number 820 fits into 6400 7 times, leaving a remainder of 660.
Put 7 as the next digit of the answer. 
Result so far: 37412.037
Deduct 5740 from 6400 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 12:
6600 divided by 820 is 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 37412.0378
If we subtract 6560 from 6600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
400 divided by 820 is 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 37412.0378
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 14:
If we divide 4000 by 820, we get 4 and a remainder of 720.
The next digit of our result is 4. 
Result so far: 37412.037804
Subtracting 3280 from 4000 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 15:
820 can be fit into 7200 8 times, resulting in a remainder of 640.
Write down 8 as next digit of the result. 
Result so far: 37412.0378048
If we subtract 6560 from 7200, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 16:
820 can be fit into 6400 7 times, resulting in a remainder of 660.
Put 7 as the next digit of the answer. 
Result so far: 37412.03780487
Subtracting 5740 from 6400 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

The final outcome is 37412.03780487, with a leftover of 6.6e-07.
