90085190 divided by 142 
Our goal is to divide 90085190 by 142.

Step 1:
142 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 142

Moving on to step 2:
If we divide 90 by 142, we get 0 and a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Append the next digit (0) from the dividend to 90 and continue with: 900 / 142

Advancing to step 3:
142 goes into 900 6 times with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 852 from 900, we get 48.
Bring next digit (8) of the dividend behind the 48 and repeat the process: 488 / 142

Going ahead to step 4:
142 goes into 488 3 times with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtract 426 from 488 to get 62.
Append the next digit (5) from the dividend to 62 and continue with: 625 / 142

Advancing to step 5:
625 divided by 142 is 4 with a remainder of 57.
Put 4 as the next digit of the answer. 
Result so far: 634.0
Deduct 568 from 625 and we're left with 57.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 142

On to step 6:
571 divided by 142 is 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 6344.0
Subtracting 568 from 571 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 142

Advancing to step 7:
The number 142 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 63440.0
If we take 0 away from 39, we end up with 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 142

On to step 8:
142 can be fit into 390 2 times, resulting in a remainder of 106.
Write down 2 as next digit of the result. 
Result so far: 634402.0
Subtract 284 from 390 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 9:
When dividing 1060 by 142, we get 7 with a remainder of 66.
Use 7 as the next digit of our solution. 
Result so far: 634402.7
If we subtract 994 from 1060, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 10:
142 can be fit into 660 4 times, resulting in a remainder of 92.
Use 4 as the next digit of our solution. 
Result so far: 634402.74
Subtract 568 from 660 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 11:
When dividing 920 by 142, we get 6 with a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 634402.746
Deduct 852 from 920 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
142 can be fit into 680 4 times, resulting in a remainder of 112.
Record the quotient 4 as the next digit in the result. 
Result so far: 634402.7464
Subtracting 568 from 680 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 13:
142 goes into 1120 7 times with a remainder of 126.
Record the quotient 7 as the next digit in the result. 
Result so far: 634402.74647
Subtracting 994 from 1120 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 14:
The number 142 fits into 1260 8 times, leaving a remainder of 124.
Put 8 as the next digit of the answer. 
Result so far: 634402.746478
The remainder is 124 after subtracting 1136 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 15:
When dividing 1240 by 142, we get 8 with a remainder of 104.
Record the quotient 8 as the next digit in the result. 
Result so far: 634402.7464788
Subtract 1136 from 1240 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The quotient of the division is 634402.7464788, and the remainder is 1.04e-06.
