Let's divide 39378131 by 279
Let's see how many times 279 fits into 39378131.

Advancing to step 1:
3 divided by 279 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 279

Advancing to step 2:
If we divide 39 by 279, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 279

On to step 3:
279 can be fit into 393 1 times, resulting in a remainder of 114.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 114 after subtracting 279 from 393.
Grab the next digit (7) from the dividend, add it to 114, then carry on: 1147 / 279

Advancing to step 4:
The number 279 fits into 1147 4 times, leaving a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 1116 away from 1147, we end up with 31.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 279

Advancing to step 5:
When dividing 318 by 279, we get 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 141.0
Subtracting 279 from 318 leaves us with 39.
Append the next digit (1) from the dividend to 39 and continue with: 391 / 279

Going ahead to step 6:
If we divide 391 by 279, we get 1 and a remainder of 112.
The number 1 becomes the next digit in our result. 
Result so far: 1411.0
The remainder is 112 after subtracting 279 from 391.
Bring next digit (3) of the dividend behind the 112 and repeat the process: 1123 / 279

Advancing to step 7:
279 can be fit into 1123 4 times, resulting in a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 14114.0
Subtract 1116 from 1123 to get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 279

Let's proceed to step 8:
279 goes into 71 0 times with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 141140.0
If we take 0 away from 71, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 9:
279 goes into 710 2 times with a remainder of 152.
Write down 2 as next digit of the result. 
Result so far: 141140.2
The remainder is 152 after subtracting 558 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 10:
279 goes into 1520 5 times with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 141140.25
Subtract 1395 from 1520 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 11:
1250 divided by 279 is 4 with a remainder of 134.
The number 4 becomes the next digit in our result. 
Result so far: 141140.254
If we subtract 1116 from 1250, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 12:
If we divide 1340 by 279, we get 4 and a remainder of 224.
Write down 4 as next digit of the result. 
Result so far: 141140.2544
If we take 1116 away from 1340, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The quotient of the division is 141140.2544, and the remainder is 0.00224.
