42086258 ÷ 986 
Let's see how many times 986 fits into 42086258.

Step 1:
986 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 986

Let's proceed to step 2:
When dividing 42 by 986, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 986

Step 3:
The number 986 fits into 420 0 times, leaving a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 420 leaves us with 420.
Append the next digit (8) from the dividend to 420 and continue with: 4208 / 986

Step 4:
986 goes into 4208 4 times with a remainder of 264.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 3944 from 4208, we get 264.
Include the next digit (6) from the dividend after 264, then repeat: 2646 / 986

Going ahead to step 5:
The number 986 fits into 2646 2 times, leaving a remainder of 674.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Deduct 1972 from 2646 and we're left with 674.
Fetch the next digit (2) from the dividend, attach it to 674 and continue: 6742 / 986

On to step 6:
The number 986 fits into 6742 6 times, leaving a remainder of 826.
Write down 6 as next digit of the result. 
Result so far: 426.0
Deduct 5916 from 6742 and we're left with 826.
Include the next digit (5) from the dividend after 826, then repeat: 8265 / 986

Going ahead to step 7:
8265 divided by 986 is 8 with a remainder of 377.
Write down 8 as next digit of the result. 
Result so far: 4268.0
The remainder is 377 after subtracting 7888 from 8265.
Append the next digit (8) from the dividend to 377 and continue with: 3778 / 986

Going ahead to step 8:
986 can be fit into 3778 3 times, resulting in a remainder of 820.
The next digit of our result is 3. 
Result so far: 42683.0
Deduct 2958 from 3778 and we're left with 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Advancing to step 9:
The number 986 fits into 8200 8 times, leaving a remainder of 312.
Write down 8 as next digit of the result. 
Result so far: 42683.8
If we subtract 7888 from 8200, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 10:
If we divide 3120 by 986, we get 3 and a remainder of 162.
Write down 3 as next digit of the result. 
Result so far: 42683.83
Deduct 2958 from 3120 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 11:
If we divide 1620 by 986, we get 1 and a remainder of 634.
Write down 1 as next digit of the result. 
Result so far: 42683.831
If we take 986 away from 1620, we end up with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Moving on to step 12:
When dividing 6340 by 986, we get 6 with a remainder of 424.
Record the quotient 6 as the next digit in the result. 
Result so far: 42683.8316
Subtract 5916 from 6340 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Step 13:
If we divide 4240 by 986, we get 4 and a remainder of 296.
Use 4 as the next digit of our solution. 
Result so far: 42683.83164
Subtracting 3944 from 4240 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Step 14:
986 can be fit into 2960 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 42683.831643
If we take 2958 away from 2960, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 15:
The number 986 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 42683.831643
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 16:
If we divide 200 by 986, we get 0 and a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 42683.831643
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 42683.831643 and a remainder of 2e-07.
