86394832 ÷ 142 
Let's see how many times 142 fits into 86394832.

Let's proceed to step 1:
When dividing 8 by 142, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 142

On to step 2:
When dividing 86 by 142, we get 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Include the next digit (3) from the dividend after 86, then repeat: 863 / 142

Going ahead to step 3:
If we divide 863 by 142, we get 6 and a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 852 from 863 and we're left with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 142

Going ahead to step 4:
If we divide 119 by 142, we get 0 and a remainder of 119.
The next digit of our result is 0. 
Result so far: 60.0
If we take 0 away from 119, we end up with 119.
Fetch the next digit (4) from the dividend, attach it to 119 and continue: 1194 / 142

Going ahead to step 5:
142 can be fit into 1194 8 times, resulting in a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 608.0
Deduct 1136 from 1194 and we're left with 58.
Take the next digit (8) from the dividend and append it to 58, then repeat: 588 / 142

Advancing to step 6:
If we divide 588 by 142, we get 4 and a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 6084.0
Subtracting 568 from 588 leaves us with 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 142

Let's proceed to step 7:
203 divided by 142 is 1 with a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 60841.0
Deduct 142 from 203 and we're left with 61.
Take the next digit (2) from the dividend and append it to 61, then repeat: 612 / 142

Going ahead to step 8:
612 divided by 142 is 4 with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 608414.0
Deduct 568 from 612 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
If we divide 440 by 142, we get 3 and a remainder of 14.
The next digit of our result is 3. 
Result so far: 608414.3
The remainder is 14 after subtracting 426 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
142 goes into 140 0 times with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 608414.3
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
When dividing 1400 by 142, we get 9 with a remainder of 122.
Write down 9 as next digit of the result. 
Result so far: 608414.309
If we subtract 1278 from 1400, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 12:
142 can be fit into 1220 8 times, resulting in a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 608414.3098
If we take 1136 away from 1220, 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.

Moving on to step 13:
142 goes into 840 5 times with a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 608414.30985
If we take 710 away from 840, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 14:
The number 142 fits into 1300 9 times, leaving a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 608414.309859
If we take 1278 away from 1300, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 15:
When dividing 220 by 142, we get 1 with a remainder of 78.
Put 1 as the next digit of the answer. 
Result so far: 608414.3098591
Deduct 142 from 220 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 16:
When dividing 780 by 142, we get 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 608414.30985915
Deduct 710 from 780 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 608414.30985915 with a remainder of 7e-08.
