Let's divide 86915730 by 142
We want to figure out the number of times 86915730 can be divided by 142.

Step 1:
The number 142 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 142

Going ahead to step 2:
The number 142 fits into 86 0 times, leaving a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 142

Step 3:
If we divide 869 by 142, we get 6 and a remainder of 17.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 852 from 869 to get 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 142

Going ahead to step 4:
When dividing 171 by 142, we get 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 61.0
If we take 142 away from 171, we end up with 29.
Take the next digit (5) from the dividend and append it to 29, then repeat: 295 / 142

Let's proceed to step 5:
295 divided by 142 is 2 with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 612.0
The remainder is 11 after subtracting 284 from 295.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 142

Going ahead to step 6:
142 can be fit into 117 0 times, resulting in a remainder of 117.
Put 0 as the next digit of the answer. 
Result so far: 6120.0
If we subtract 0 from 117, we get 117.
Take the next digit (3) from the dividend and append it to 117, then repeat: 1173 / 142

Let's proceed to step 7:
When dividing 1173 by 142, we get 8 with a remainder of 37.
The next digit of our result is 8. 
Result so far: 61208.0
Deduct 1136 from 1173 and we're left with 37.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 142

Advancing to step 8:
142 can be fit into 370 2 times, resulting in a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 612082.0
Deduct 284 from 370 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 9:
142 can be fit into 860 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 612082.6
If we take 852 away from 860, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
When dividing 80 by 142, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 612082.6
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
800 divided by 142 is 5 with a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 612082.605
Subtracting 710 from 800 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 12:
The number 142 fits into 900 6 times, leaving a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 612082.6056
Subtract 852 from 900 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
The number 142 fits into 480 3 times, leaving a remainder of 54.
Use 3 as the next digit of our solution. 
Result so far: 612082.60563
Deduct 426 from 480 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 14:
142 goes into 540 3 times with a remainder of 114.
Write down 3 as next digit of the result. 
Result so far: 612082.605633
Subtracting 426 from 540 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Our division results in 612082.605633 with a remaining 1.14e-05.
