We divide 42993979 by 139
We want to figure out the number of times 42993979 can be divided by 139.

Step 1:
If we divide 4 by 139, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 139

Advancing to step 2:
If we divide 42 by 139, we get 0 and a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 139

Let's proceed to step 3:
The number 139 fits into 429 3 times, leaving a remainder of 12.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 417 from 429 leaves us with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 139

On to step 4:
The number 139 fits into 129 0 times, leaving a remainder of 129.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we subtract 0 from 129, we get 129.
Fetch the next digit (3) from the dividend, attach it to 129 and continue: 1293 / 139

Moving on to step 5:
If we divide 1293 by 139, we get 9 and a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 309.0
Subtracting 1251 from 1293 leaves us with 42.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 139

Step 6:
429 divided by 139 is 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 3093.0
Subtracting 417 from 429 leaves us with 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 139

Going ahead to step 7:
The number 139 fits into 127 0 times, leaving a remainder of 127.
Use 0 as the next digit of our solution. 
Result so far: 30930.0
Deduct 0 from 127 and we're left with 127.
Take the next digit (9) from the dividend and append it to 127, then repeat: 1279 / 139

Step 8:
139 can be fit into 1279 9 times, resulting in a remainder of 28.
The next digit of our result is 9. 
Result so far: 309309.0
The remainder is 28 after subtracting 1251 from 1279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
280 divided by 139 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 309309.2
The remainder is 2 after subtracting 278 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
When dividing 20 by 139, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 309309.2
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
The number 139 fits into 200 1 times, leaving a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 309309.201
Subtracting 139 from 200 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 12:
610 divided by 139 is 4 with a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 309309.2014
The remainder is 54 after subtracting 556 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 13:
The number 139 fits into 540 3 times, leaving a remainder of 123.
Write down 3 as next digit of the result. 
Result so far: 309309.20143
If we subtract 417 from 540, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 14:
1230 divided by 139 is 8 with a remainder of 118.
The next digit of our result is 8. 
Result so far: 309309.201438
Subtracting 1112 from 1230 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 15:
If we divide 1180 by 139, we get 8 and a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 309309.2014388
Deduct 1112 from 1180 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Our division results in 309309.2014388 with a remaining 6.8e-07.
