Let's divide 90194462 by 642
We're looking to find how many times 642 goes into 90194462.

Step 1:
642 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 / 642

Advancing to step 2:
When dividing 90 by 642, we get 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Append the next digit (1) from the dividend to 90 and continue with: 901 / 642

Let's proceed to step 3:
642 goes into 901 1 times with a remainder of 259.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 642 from 901 to get 259.
Append the next digit (9) from the dividend to 259 and continue with: 2599 / 642

Advancing to step 4:
If we divide 2599 by 642, we get 4 and a remainder of 31.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 2568 away from 2599, we end up with 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 642

Advancing to step 5:
314 divided by 642 is 0 with a remainder of 314.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
If we subtract 0 from 314, we get 314.
Include the next digit (4) from the dividend after 314, then repeat: 3144 / 642

On to step 6:
If we divide 3144 by 642, we get 4 and a remainder of 576.
The next digit of our result is 4. 
Result so far: 1404.0
Deduct 2568 from 3144 and we're left with 576.
Include the next digit (6) from the dividend after 576, then repeat: 5766 / 642

Going ahead to step 7:
5766 divided by 642 is 8 with a remainder of 630.
Put 8 as the next digit of the answer. 
Result so far: 14048.0
The remainder is 630 after subtracting 5136 from 5766.
Fetch the next digit (2) from the dividend, attach it to 630 and continue: 6302 / 642

Advancing to step 8:
6302 divided by 642 is 9 with a remainder of 524.
The number 9 becomes the next digit in our result. 
Result so far: 140489.0
Subtracting 5778 from 6302 leaves us with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Going ahead to step 9:
5240 divided by 642 is 8 with a remainder of 104.
The number 8 becomes the next digit in our result. 
Result so far: 140489.8
Subtracting 5136 from 5240 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 10:
1040 divided by 642 is 1 with a remainder of 398.
Record the quotient 1 as the next digit in the result. 
Result so far: 140489.81
Deduct 642 from 1040 and we're left with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 11:
642 goes into 3980 6 times with a remainder of 128.
The number 6 becomes the next digit in our result. 
Result so far: 140489.816
If we subtract 3852 from 3980, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 12:
If we divide 1280 by 642, we get 1 and a remainder of 638.
Use 1 as the next digit of our solution. 
Result so far: 140489.8161
Subtracting 642 from 1280 leaves us with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

On to step 13:
642 goes into 6380 9 times with a remainder of 602.
Write down 9 as next digit of the result. 
Result so far: 140489.81619
The remainder is 602 after subtracting 5778 from 6380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Advancing to step 14:
When dividing 6020 by 642, we get 9 with a remainder of 242.
Write down 9 as next digit of the result. 
Result so far: 140489.816199
Subtracting 5778 from 6020 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

The final outcome is 140489.816199, with a leftover of 2.42e-05.
