We look at the division of 42686037 by 279 
We want to divide 42686037 by 279.

Let's proceed to step 1:
When dividing 4 by 279, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 279

Step 2:
279 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Take the next digit (6) from the dividend and append it to 42, then repeat: 426 / 279

Step 3:
279 goes into 426 1 times with a remainder of 147.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 279 from 426 leaves us with 147.
Include the next digit (8) from the dividend after 147, then repeat: 1478 / 279

Advancing to step 4:
279 can be fit into 1478 5 times, resulting in a remainder of 83.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 83 after subtracting 1395 from 1478.
Bring next digit (6) of the dividend behind the 83 and repeat the process: 836 / 279

Advancing to step 5:
279 can be fit into 836 2 times, resulting in a remainder of 278.
Put 2 as the next digit of the answer. 
Result so far: 152.0
If we subtract 558 from 836, we get 278.
Fetch the next digit (0) from the dividend, attach it to 278 and continue: 2780 / 279

Going ahead to step 6:
279 can be fit into 2780 9 times, resulting in a remainder of 269.
Put 9 as the next digit of the answer. 
Result so far: 1529.0
Subtracting 2511 from 2780 leaves us with 269.
Bring next digit (3) of the dividend behind the 269 and repeat the process: 2693 / 279

On to step 7:
If we divide 2693 by 279, we get 9 and a remainder of 182.
The next digit of our result is 9. 
Result so far: 15299.0
Subtract 2511 from 2693 to get 182.
Take the next digit (7) from the dividend and append it to 182, then repeat: 1827 / 279

Moving on to step 8:
The number 279 fits into 1827 6 times, leaving a remainder of 153.
The number 6 becomes the next digit in our result. 
Result so far: 152996.0
Subtract 1674 from 1827 to get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 9:
1530 divided by 279 is 5 with a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 152996.5
The remainder is 135 after subtracting 1395 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 10:
When dividing 1350 by 279, we get 4 with a remainder of 234.
Put 4 as the next digit of the answer. 
Result so far: 152996.54
Subtract 1116 from 1350 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 11:
279 goes into 2340 8 times with a remainder of 108.
Put 8 as the next digit of the answer. 
Result so far: 152996.548
Subtracting 2232 from 2340 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 12:
279 goes into 1080 3 times with a remainder of 243.
Record the quotient 3 as the next digit in the result. 
Result so far: 152996.5483
The remainder is 243 after subtracting 837 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Moving on to step 13:
2430 divided by 279 is 8 with a remainder of 198.
Write down 8 as next digit of the result. 
Result so far: 152996.54838
Deduct 2232 from 2430 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 14:
When dividing 1980 by 279, we get 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 152996.548387
Subtract 1953 from 1980 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 15:
270 divided by 279 is 0 with a remainder of 270.
Record the quotient 0 as the next digit in the result. 
Result so far: 152996.548387
The remainder is 270 after subtracting 0 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 16:
If we divide 2700 by 279, we get 9 and a remainder of 189.
The next digit of our result is 9. 
Result so far: 152996.54838709
If we take 2511 away from 2700, we end up 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.

The final result is 152996.54838709 with a remainder of 1.89e-07.
