90162270 divided by 638 
We want to divide 90162270 by 638.

Going ahead to step 1:
When dividing 9 by 638, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 638

Moving on to step 2:
90 divided by 638 is 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Grab the next digit (1) from the dividend, add it to 90, then carry on: 901 / 638

On to step 3:
If we divide 901 by 638, we get 1 and a remainder of 263.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 638 from 901 to get 263.
Grab the next digit (6) from the dividend, add it to 263, then carry on: 2636 / 638

Advancing to step 4:
638 can be fit into 2636 4 times, resulting in a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 2552 from 2636 and we're left with 84.
Append the next digit (2) from the dividend to 84 and continue with: 842 / 638

Advancing to step 5:
If we divide 842 by 638, we get 1 and a remainder of 204.
The next digit of our result is 1. 
Result so far: 141.0
The remainder is 204 after subtracting 638 from 842.
Bring next digit (2) of the dividend behind the 204 and repeat the process: 2042 / 638

Let's proceed to step 6:
The number 638 fits into 2042 3 times, leaving a remainder of 128.
The next digit of our result is 3. 
Result so far: 1413.0
Deduct 1914 from 2042 and we're left with 128.
Fetch the next digit (7) from the dividend, attach it to 128 and continue: 1287 / 638

Going ahead to step 7:
1287 divided by 638 is 2 with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 14132.0
Deduct 1276 from 1287 and we're left with 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 638

On to step 8:
110 divided by 638 is 0 with a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 141320.0
The remainder is 110 after subtracting 0 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 9:
638 goes into 1100 1 times with a remainder of 462.
The next digit of our result is 1. 
Result so far: 141320.1
If we take 638 away from 1100, we end up with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Moving on to step 10:
638 goes into 4620 7 times with a remainder of 154.
The number 7 becomes the next digit in our result. 
Result so far: 141320.17
If we take 4466 away from 4620, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 11:
When dividing 1540 by 638, we get 2 with a remainder of 264.
Use 2 as the next digit of our solution. 
Result so far: 141320.172
Subtract 1276 from 1540 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 12:
638 goes into 2640 4 times with a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 141320.1724
Subtract 2552 from 2640 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 13:
638 goes into 880 1 times with a remainder of 242.
The number 1 becomes the next digit in our result. 
Result so far: 141320.17241
Subtracting 638 from 880 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.

Step 14:
2420 divided by 638 is 3 with a remainder of 506.
Write down 3 as next digit of the result. 
Result so far: 141320.172413
If we take 1914 away from 2420, we end up with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Step 15:
If we divide 5060 by 638, we get 7 and a remainder of 594.
Write down 7 as next digit of the result. 
Result so far: 141320.1724137
Deduct 4466 from 5060 and we're left with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Moving on to step 16:
The number 638 fits into 5940 9 times, leaving a remainder of 198.
Write down 9 as next digit of the result. 
Result so far: 141320.17241379
Subtracting 5742 from 5940 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Our division results in 141320.17241379 with a remaining 1.98e-07.
