We divide 17139868 by 142
We want to divide 17139868 by 142.

Advancing to step 1:
When dividing 1 by 142, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 142

Step 2:
If we divide 17 by 142, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 142

Moving on to step 3:
If we divide 171 by 142, we get 1 and a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 29 after subtracting 142 from 171.
Append the next digit (3) from the dividend to 29 and continue with: 293 / 142

Advancing to step 4:
The number 142 fits into 293 2 times, leaving a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 284 away from 293, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 142

Advancing to step 5:
142 can be fit into 99 0 times, resulting in a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 120.0
If we subtract 0 from 99, we get 99.
Append the next digit (8) from the dividend to 99 and continue with: 998 / 142

Step 6:
998 divided by 142 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 1207.0
If we subtract 994 from 998, we get 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 142

Let's proceed to step 7:
If we divide 46 by 142, we get 0 and a remainder of 46.
Write down 0 as next digit of the result. 
Result so far: 12070.0
Deduct 0 from 46 and we're left with 46.
Append the next digit (8) from the dividend to 46 and continue with: 468 / 142

Step 8:
If we divide 468 by 142, we get 3 and a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 120703.0
Subtracting 426 from 468 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
The number 142 fits into 420 2 times, leaving a remainder of 136.
Put 2 as the next digit of the answer. 
Result so far: 120703.2
Subtracting 284 from 420 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 10:
If we divide 1360 by 142, we get 9 and a remainder of 82.
Put 9 as the next digit of the answer. 
Result so far: 120703.29
The remainder is 82 after subtracting 1278 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 11:
142 can be fit into 820 5 times, resulting in a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 120703.295
If we take 710 away from 820, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 12:
142 can be fit into 1100 7 times, resulting in a remainder of 106.
The number 7 becomes the next digit in our result. 
Result so far: 120703.2957
If we subtract 994 from 1100, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 13:
142 goes into 1060 7 times with a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 120703.29577
If we subtract 994 from 1060, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

After the division, we end up with 120703.29577 and a remainder of 6.6e-05.
