66090827 ÷ 142 
Our goal is to divide 66090827 by 142.

Going ahead to step 1:
6 divided by 142 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 142

Going ahead to step 2:
142 goes into 66 0 times with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Take the next digit (0) from the dividend and append it to 66, then repeat: 660 / 142

Moving on to step 3:
When dividing 660 by 142, we get 4 with a remainder of 92.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 568 from 660, we get 92.
Append the next digit (9) from the dividend to 92 and continue with: 929 / 142

On to step 4:
If we divide 929 by 142, we get 6 and a remainder of 77.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Subtracting 852 from 929 leaves us with 77.
Take the next digit (0) from the dividend and append it to 77, then repeat: 770 / 142

Moving on to step 5:
The number 142 fits into 770 5 times, leaving a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 465.0
The remainder is 60 after subtracting 710 from 770.
Bring next digit (8) of the dividend behind the 60 and repeat the process: 608 / 142

Moving on to step 6:
When dividing 608 by 142, we get 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 4654.0
Subtracting 568 from 608 leaves us with 40.
Include the next digit (2) from the dividend after 40, then repeat: 402 / 142

Let's proceed to step 7:
If we divide 402 by 142, we get 2 and a remainder of 118.
Write down 2 as next digit of the result. 
Result so far: 46542.0
If we subtract 284 from 402, we get 118.
Include the next digit (7) from the dividend after 118, then repeat: 1187 / 142

On to step 8:
When dividing 1187 by 142, we get 8 with a remainder of 51.
The next digit of our result is 8. 
Result so far: 465428.0
Subtracting 1136 from 1187 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 9:
142 can be fit into 510 3 times, resulting in a remainder of 84.
Put 3 as the next digit of the answer. 
Result so far: 465428.3
Deduct 426 from 510 and we're left 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.

Advancing to step 10:
142 goes into 840 5 times with a remainder of 130.
The next digit of our result is 5. 
Result so far: 465428.35
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 11:
142 can be fit into 1300 9 times, resulting in a remainder of 22.
The next digit of our result is 9. 
Result so far: 465428.359
Deduct 1278 from 1300 and we're left 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.

Let's proceed to step 12:
If we divide 220 by 142, we get 1 and a remainder of 78.
The next digit of our result is 1. 
Result so far: 465428.3591
The remainder is 78 after subtracting 142 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 13:
142 can be fit into 780 5 times, resulting in a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 465428.35915
Subtract 710 from 780 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 14:
When dividing 700 by 142, we get 4 with a remainder of 132.
The next digit of our result is 4. 
Result so far: 465428.359154
Subtract 568 from 700 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 15:
When dividing 1320 by 142, we get 9 with a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 465428.3591549
Deduct 1278 from 1320 and we're left 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.

Let's proceed to step 16:
420 divided by 142 is 2 with a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 465428.35915492
If we subtract 284 from 420, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

After the division, we end up with 465428.35915492 and a remainder of 1.36e-07.
