13800839 ÷ 681 
Let's see how many times 681 fits into 13800839.

On to step 1:
1 divided by 681 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 681

On to step 2:
If we divide 13 by 681, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 681

Advancing to step 3:
138 divided by 681 is 0 with a remainder of 138.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 138 leaves us with 138.
Fetch the next digit (0) from the dividend, attach it to 138 and continue: 1380 / 681

On to step 4:
681 goes into 1380 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 18 after subtracting 1362 from 1380.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 681

Advancing to step 5:
681 can be fit into 180 0 times, resulting in a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 180 to get 180.
Take the next digit (8) from the dividend and append it to 180, then repeat: 1808 / 681

Going ahead to step 6:
681 can be fit into 1808 2 times, resulting in a remainder of 446.
Put 2 as the next digit of the answer. 
Result so far: 202.0
Subtract 1362 from 1808 to get 446.
Include the next digit (3) from the dividend after 446, then repeat: 4463 / 681

Step 7:
When dividing 4463 by 681, we get 6 with a remainder of 377.
Use 6 as the next digit of our solution. 
Result so far: 2026.0
If we subtract 4086 from 4463, we get 377.
Append the next digit (9) from the dividend to 377 and continue with: 3779 / 681

Let's proceed to step 8:
When dividing 3779 by 681, we get 5 with a remainder of 374.
Put 5 as the next digit of the answer. 
Result so far: 20265.0
Subtracting 3405 from 3779 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Going ahead to step 9:
When dividing 3740 by 681, we get 5 with a remainder of 335.
Put 5 as the next digit of the answer. 
Result so far: 20265.5
Subtract 3405 from 3740 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 10:
When dividing 3350 by 681, we get 4 with a remainder of 626.
Use 4 as the next digit of our solution. 
Result so far: 20265.54
Deduct 2724 from 3350 and we're left with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Advancing to step 11:
If we divide 6260 by 681, we get 9 and a remainder of 131.
The next digit of our result is 9. 
Result so far: 20265.549
Subtract 6129 from 6260 to get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 12:
If we divide 1310 by 681, we get 1 and a remainder of 629.
Record the quotient 1 as the next digit in the result. 
Result so far: 20265.5491
If we take 681 away from 1310, we end up with 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

Moving on to step 13:
681 goes into 6290 9 times with a remainder of 161.
Put 9 as the next digit of the answer. 
Result so far: 20265.54919
Deduct 6129 from 6290 and we're left with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Going ahead to step 14:
681 goes into 1610 2 times with a remainder of 248.
Record the quotient 2 as the next digit in the result. 
Result so far: 20265.549192
Subtract 1362 from 1610 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 15:
If we divide 2480 by 681, we get 3 and a remainder of 437.
Use 3 as the next digit of our solution. 
Result so far: 20265.5491923
Subtracting 2043 from 2480 leaves us with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Moving on to step 16:
If we divide 4370 by 681, we get 6 and a remainder of 284.
The number 6 becomes the next digit in our result. 
Result so far: 20265.54919236
If we take 4086 away from 4370, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

After the division, we end up with 20265.54919236 and a remainder of 2.84e-07.
