We're dividing 42582120 by 276 
We want to figure out the number of times 42582120 can be divided by 276.

Moving on to step 1:
When dividing 4 by 276, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 276

Moving on to step 2:
276 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 276

Moving on to step 3:
276 goes into 425 1 times with a remainder of 149.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 276 from 425 and we're left with 149.
Take the next digit (8) from the dividend and append it to 149, then repeat: 1498 / 276

Let's proceed to step 4:
276 goes into 1498 5 times with a remainder of 118.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 118 after subtracting 1380 from 1498.
Include the next digit (2) from the dividend after 118, then repeat: 1182 / 276

Going ahead to step 5:
276 goes into 1182 4 times with a remainder of 78.
The next digit of our result is 4. 
Result so far: 154.0
Deduct 1104 from 1182 and we're left with 78.
Take the next digit (1) from the dividend and append it to 78, then repeat: 781 / 276

Advancing to step 6:
The number 276 fits into 781 2 times, leaving a remainder of 229.
The number 2 becomes the next digit in our result. 
Result so far: 1542.0
If we subtract 552 from 781, we get 229.
Take the next digit (2) from the dividend and append it to 229, then repeat: 2292 / 276

Advancing to step 7:
If we divide 2292 by 276, we get 8 and a remainder of 84.
The number 8 becomes the next digit in our result. 
Result so far: 15428.0
If we subtract 2208 from 2292, we get 84.
Include the next digit (0) from the dividend after 84, then repeat: 840 / 276

Moving on to step 8:
When dividing 840 by 276, we get 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 154283.0
Subtract 828 from 840 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
120 divided by 276 is 0 with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 154283.0
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 10:
The number 276 fits into 1200 4 times, leaving a remainder of 96.
Record the quotient 4 as the next digit in the result. 
Result so far: 154283.04
Deduct 1104 from 1200 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 11:
276 goes into 960 3 times with a remainder of 132.
Put 3 as the next digit of the answer. 
Result so far: 154283.043
If we take 828 away from 960, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 12:
If we divide 1320 by 276, we get 4 and a remainder of 216.
Put 4 as the next digit of the answer. 
Result so far: 154283.0434
Subtracting 1104 from 1320 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 13:
The number 276 fits into 2160 7 times, leaving a remainder of 228.
Record the quotient 7 as the next digit in the result. 
Result so far: 154283.04347
Subtracting 1932 from 2160 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 14:
When dividing 2280 by 276, we get 8 with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 154283.043478
If we take 2208 away from 2280, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 15:
When dividing 720 by 276, we get 2 with a remainder of 168.
Put 2 as the next digit of the answer. 
Result so far: 154283.0434782
Subtract 552 from 720 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 16:
When dividing 1680 by 276, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 154283.04347826
Deduct 1656 from 1680 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 154283.04347826, and the remainder is 2.4e-08.
