70881511 ÷ 142 
We want to figure out the number of times 70881511 can be divided by 142.

Let's proceed to step 1:
If we divide 7 by 142, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 142

Advancing to step 2:
70 divided by 142 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Grab the next digit (8) from the dividend, add it to 70, then carry on: 708 / 142

Moving on to step 3:
142 can be fit into 708 4 times, resulting in a remainder of 140.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 568 from 708 leaves us with 140.
Bring next digit (8) of the dividend behind the 140 and repeat the process: 1408 / 142

Step 4:
142 can be fit into 1408 9 times, resulting in a remainder of 130.
Use 9 as the next digit of our solution. 
Result so far: 49.0
If we take 1278 away from 1408, we end up with 130.
Grab the next digit (1) from the dividend, add it to 130, then carry on: 1301 / 142

Going ahead to step 5:
142 can be fit into 1301 9 times, resulting in a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 499.0
The remainder is 23 after subtracting 1278 from 1301.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 142

Let's proceed to step 6:
When dividing 235 by 142, we get 1 with a remainder of 93.
The number 1 becomes the next digit in our result. 
Result so far: 4991.0
If we subtract 142 from 235, we get 93.
Append the next digit (1) from the dividend to 93 and continue with: 931 / 142

Let's proceed to step 7:
The number 142 fits into 931 6 times, leaving a remainder of 79.
The number 6 becomes the next digit in our result. 
Result so far: 49916.0
If we subtract 852 from 931, we get 79.
Grab the next digit (1) from the dividend, add it to 79, then carry on: 791 / 142

On to step 8:
142 can be fit into 791 5 times, resulting in a remainder of 81.
Use 5 as the next digit of our solution. 
Result so far: 499165.0
If we take 710 away from 791, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 9:
The number 142 fits into 810 5 times, leaving a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 499165.5
Deduct 710 from 810 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 10:
When dividing 1000 by 142, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 499165.57
If we take 994 away from 1000, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
142 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 499165.57
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
The number 142 fits into 600 4 times, leaving a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 499165.5704
If we subtract 568 from 600, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
142 can be fit into 320 2 times, resulting in a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 499165.57042
If we take 284 away from 320, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 14:
142 can be fit into 360 2 times, resulting in a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 499165.570422
The remainder is 76 after subtracting 284 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 499165.570422 and a remainder of 7.6e-06.
