We're dividing 42081420 by 987 
Let's see how many times 987 fits into 42081420.

Going ahead to step 1:
987 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 987

Going ahead to step 2:
The number 987 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 987

On to step 3:
420 divided by 987 is 0 with a remainder of 420.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 420 leaves us with 420.
Grab the next digit (8) from the dividend, add it to 420, then carry on: 4208 / 987

Step 4:
When dividing 4208 by 987, we get 4 with a remainder of 260.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 3948 from 4208, we get 260.
Bring next digit (1) of the dividend behind the 260 and repeat the process: 2601 / 987

Let's proceed to step 5:
If we divide 2601 by 987, we get 2 and a remainder of 627.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we take 1974 away from 2601, we end up with 627.
Include the next digit (4) from the dividend after 627, then repeat: 6274 / 987

Let's proceed to step 6:
The number 987 fits into 6274 6 times, leaving a remainder of 352.
Record the quotient 6 as the next digit in the result. 
Result so far: 426.0
Subtract 5922 from 6274 to get 352.
Take the next digit (2) from the dividend and append it to 352, then repeat: 3522 / 987

Step 7:
The number 987 fits into 3522 3 times, leaving a remainder of 561.
The number 3 becomes the next digit in our result. 
Result so far: 4263.0
If we take 2961 away from 3522, we end up with 561.
Include the next digit (0) from the dividend after 561, then repeat: 5610 / 987

Advancing to step 8:
The number 987 fits into 5610 5 times, leaving a remainder of 675.
Write down 5 as next digit of the result. 
Result so far: 42635.0
If we take 4935 away from 5610, we end up with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Step 9:
The number 987 fits into 6750 6 times, leaving a remainder of 828.
The next digit of our result is 6. 
Result so far: 42635.6
If we subtract 5922 from 6750, we get 828.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8280, and continue the process.

Let's proceed to step 10:
When dividing 8280 by 987, we get 8 with a remainder of 384.
The number 8 becomes the next digit in our result. 
Result so far: 42635.68
Subtracting 7896 from 8280 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 11:
If we divide 3840 by 987, we get 3 and a remainder of 879.
Put 3 as the next digit of the answer. 
Result so far: 42635.683
If we subtract 2961 from 3840, we get 879.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8790, and continue the process.

Advancing to step 12:
If we divide 8790 by 987, we get 8 and a remainder of 894.
Put 8 as the next digit of the answer. 
Result so far: 42635.6838
If we subtract 7896 from 8790, we get 894.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8940, and continue the process.

On to step 13:
If we divide 8940 by 987, we get 9 and a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 42635.68389
The remainder is 57 after subtracting 8883 from 8940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 14:
987 goes into 570 0 times with a remainder of 570.
Record the quotient 0 as the next digit in the result. 
Result so far: 42635.68389
Subtract 0 from 570 to get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Advancing to step 15:
If we divide 5700 by 987, we get 5 and a remainder of 765.
Record the quotient 5 as the next digit in the result. 
Result so far: 42635.6838905
If we take 4935 away from 5700, we end up with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

On to step 16:
If we divide 7650 by 987, we get 7 and a remainder of 741.
Use 7 as the next digit of our solution. 
Result so far: 42635.68389057
Subtracting 6909 from 7650 leaves us with 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7410, and continue the process.

The final outcome is 42635.68389057, with a leftover of 7.41e-07.
