31179190 ÷ 139 
We want to figure out the number of times 31179190 can be divided by 139.

On to step 1:
The number 139 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 139

On to step 2:
When dividing 31 by 139, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 139

Going ahead to step 3:
The number 139 fits into 311 2 times, leaving a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 278 from 311, we get 33.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 139

Step 4:
139 can be fit into 337 2 times, resulting in a remainder of 59.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtracting 278 from 337 leaves us with 59.
Append the next digit (9) from the dividend to 59 and continue with: 599 / 139

Advancing to step 5:
The number 139 fits into 599 4 times, leaving a remainder of 43.
The next digit of our result is 4. 
Result so far: 224.0
The remainder is 43 after subtracting 556 from 599.
Take the next digit (1) from the dividend and append it to 43, then repeat: 431 / 139

Going ahead to step 6:
139 goes into 431 3 times with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 2243.0
If we subtract 417 from 431, we get 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 139

On to step 7:
When dividing 149 by 139, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 22431.0
Subtracting 139 from 149 leaves us with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 139

Going ahead to step 8:
100 divided by 139 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 224310.0
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 9:
The number 139 fits into 1000 7 times, leaving a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 224310.7
The remainder is 27 after subtracting 973 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 10:
If we divide 270 by 139, we get 1 and a remainder of 131.
Record the quotient 1 as the next digit in the result. 
Result so far: 224310.71
Deduct 139 from 270 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 11:
The number 139 fits into 1310 9 times, leaving a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 224310.719
Subtract 1251 from 1310 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 12:
139 goes into 590 4 times with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 224310.7194
If we take 556 away from 590, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 13:
If we divide 340 by 139, we get 2 and a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 224310.71942
If we take 278 away from 340, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 14:
If we divide 620 by 139, we get 4 and a remainder of 64.
The next digit of our result is 4. 
Result so far: 224310.719424
The remainder is 64 after subtracting 556 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 15:
139 can be fit into 640 4 times, resulting in a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 224310.7194244
If we take 556 away from 640, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The quotient of the division is 224310.7194244, and the remainder is 8.4e-07.
