42438519 ÷ 681 
Our goal is to divide 42438519 by 681.

Going ahead to step 1:
When dividing 4 by 681, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 681

Advancing to step 2:
42 divided by 681 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (4) from the dividend, add it to 42, then carry on: 424 / 681

Advancing to step 3:
424 divided by 681 is 0 with a remainder of 424.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 424, we get 424.
Include the next digit (3) from the dividend after 424, then repeat: 4243 / 681

Advancing to step 4:
4243 divided by 681 is 6 with a remainder of 157.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 4086 from 4243 to get 157.
Grab the next digit (8) from the dividend, add it to 157, then carry on: 1578 / 681

Going ahead to step 5:
The number 681 fits into 1578 2 times, leaving a remainder of 216.
Put 2 as the next digit of the answer. 
Result so far: 62.0
If we subtract 1362 from 1578, we get 216.
Append the next digit (5) from the dividend to 216 and continue with: 2165 / 681

Going ahead to step 6:
681 goes into 2165 3 times with a remainder of 122.
The next digit of our result is 3. 
Result so far: 623.0
Subtracting 2043 from 2165 leaves us with 122.
Take the next digit (1) from the dividend and append it to 122, then repeat: 1221 / 681

Step 7:
1221 divided by 681 is 1 with a remainder of 540.
The number 1 becomes the next digit in our result. 
Result so far: 6231.0
If we subtract 681 from 1221, we get 540.
Take the next digit (9) from the dividend and append it to 540, then repeat: 5409 / 681

Advancing to step 8:
If we divide 5409 by 681, we get 7 and a remainder of 642.
The number 7 becomes the next digit in our result. 
Result so far: 62317.0
If we subtract 4767 from 5409, we get 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Let's proceed to step 9:
6420 divided by 681 is 9 with a remainder of 291.
The next digit of our result is 9. 
Result so far: 62317.9
If we take 6129 away from 6420, we end up with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Advancing to step 10:
The number 681 fits into 2910 4 times, leaving a remainder of 186.
The number 4 becomes the next digit in our result. 
Result so far: 62317.94
Subtract 2724 from 2910 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 11:
1860 divided by 681 is 2 with a remainder of 498.
Use 2 as the next digit of our solution. 
Result so far: 62317.942
If we take 1362 away from 1860, we end up with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Moving on to step 12:
If we divide 4980 by 681, we get 7 and a remainder of 213.
The number 7 becomes the next digit in our result. 
Result so far: 62317.9427
The remainder is 213 after subtracting 4767 from 4980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Moving on to step 13:
2130 divided by 681 is 3 with a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 62317.94273
If we subtract 2043 from 2130, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 14:
When dividing 870 by 681, we get 1 with a remainder of 189.
The number 1 becomes the next digit in our result. 
Result so far: 62317.942731
Deduct 681 from 870 and we're left with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 15:
681 goes into 1890 2 times with a remainder of 528.
The number 2 becomes the next digit in our result. 
Result so far: 62317.9427312
Deduct 1362 from 1890 and we're left with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Going ahead to step 16:
5280 divided by 681 is 7 with a remainder of 513.
Use 7 as the next digit of our solution. 
Result so far: 62317.94273127
The remainder is 513 after subtracting 4767 from 5280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

After the division, we end up with 62317.94273127 and a remainder of 5.13e-07.
