42841258 ÷ 138 
We want to figure out the number of times 42841258 can be divided by 138.

Let's proceed to step 1:
If we divide 4 by 138, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 138

On to step 2:
42 divided by 138 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 138

On to step 3:
428 divided by 138 is 3 with a remainder of 14.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 414 from 428 leaves us with 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 138

Moving on to step 4:
144 divided by 138 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 31.0
Deduct 138 from 144 and we're left with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 138

Moving on to step 5:
61 divided by 138 is 0 with a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 310.0
Deduct 0 from 61 and we're left with 61.
Fetch the next digit (2) from the dividend, attach it to 61 and continue: 612 / 138

Going ahead to step 6:
If we divide 612 by 138, we get 4 and a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 3104.0
Deduct 552 from 612 and we're left with 60.
Bring next digit (5) of the dividend behind the 60 and repeat the process: 605 / 138

Advancing to step 7:
When dividing 605 by 138, we get 4 with a remainder of 53.
Put 4 as the next digit of the answer. 
Result so far: 31044.0
Subtracting 552 from 605 leaves us with 53.
Fetch the next digit (8) from the dividend, attach it to 53 and continue: 538 / 138

On to step 8:
If we divide 538 by 138, we get 3 and a remainder of 124.
Record the quotient 3 as the next digit in the result. 
Result so far: 310443.0
Subtracting 414 from 538 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 9:
If we divide 1240 by 138, we get 8 and a remainder of 136.
Use 8 as the next digit of our solution. 
Result so far: 310443.8
Subtracting 1104 from 1240 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 10:
138 goes into 1360 9 times with a remainder of 118.
The next digit of our result is 9. 
Result so far: 310443.89
Subtract 1242 from 1360 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 11:
1180 divided by 138 is 8 with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 310443.898
Subtracting 1104 from 1180 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 12:
If we divide 760 by 138, we get 5 and a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 310443.8985
The remainder is 70 after subtracting 690 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 13:
700 divided by 138 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 310443.89855
The remainder is 10 after subtracting 690 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 310443.89855 with a remaining 1e-05.
