We're dividing 90109076 by 142 
Let's see how many times 142 fits into 90109076.

Advancing to step 1:
142 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 142

Advancing to step 2:
The number 142 fits into 90 0 times, leaving a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Bring next digit (1) of the dividend behind the 90 and repeat the process: 901 / 142

Moving on to step 3:
If we divide 901 by 142, we get 6 and a remainder of 49.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 852 from 901 to get 49.
Include the next digit (0) from the dividend after 49, then repeat: 490 / 142

Moving on to step 4:
142 can be fit into 490 3 times, resulting in a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 63.0
The remainder is 64 after subtracting 426 from 490.
Take the next digit (9) from the dividend and append it to 64, then repeat: 649 / 142

Let's proceed to step 5:
649 divided by 142 is 4 with a remainder of 81.
The next digit of our result is 4. 
Result so far: 634.0
Deduct 568 from 649 and we're left with 81.
Fetch the next digit (0) from the dividend, attach it to 81 and continue: 810 / 142

Moving on to step 6:
When dividing 810 by 142, we get 5 with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 6345.0
Subtracting 710 from 810 leaves us with 100.
Append the next digit (7) from the dividend to 100 and continue with: 1007 / 142

Going ahead to step 7:
142 goes into 1007 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 63457.0
Deduct 994 from 1007 and we're left with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 142

On to step 8:
If we divide 136 by 142, we get 0 and a remainder of 136.
Use 0 as the next digit of our solution. 
Result so far: 634570.0
Deduct 0 from 136 and we're left 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 9:
When dividing 1360 by 142, we get 9 with a remainder of 82.
Record the quotient 9 as the next digit in the result. 
Result so far: 634570.9
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.

Let's proceed to step 10:
The number 142 fits into 820 5 times, leaving a remainder of 110.
Write down 5 as next digit of the result. 
Result so far: 634570.95
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.

On to step 11:
When dividing 1100 by 142, we get 7 with a remainder of 106.
Record the quotient 7 as the next digit in the result. 
Result so far: 634570.957
The remainder is 106 after subtracting 994 from 1100.
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 12:
When dividing 1060 by 142, we get 7 with a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 634570.9577
The remainder is 66 after subtracting 994 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 634570.9577, with a leftover of 0.00066.
