We're dividing 90449072 by 638 
We want to divide 90449072 by 638.

Step 1:
638 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 638

Advancing to step 2:
If we divide 90 by 638, we get 0 and a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Bring next digit (4) of the dividend behind the 90 and repeat the process: 904 / 638

Going ahead to step 3:
If we divide 904 by 638, we get 1 and a remainder of 266.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 266 after subtracting 638 from 904.
Grab the next digit (4) from the dividend, add it to 266, then carry on: 2664 / 638

Let's proceed to step 4:
The number 638 fits into 2664 4 times, leaving a remainder of 112.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 2552 away from 2664, we end up with 112.
Grab the next digit (9) from the dividend, add it to 112, then carry on: 1129 / 638

Going ahead to step 5:
The number 638 fits into 1129 1 times, leaving a remainder of 491.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
The remainder is 491 after subtracting 638 from 1129.
Include the next digit (0) from the dividend after 491, then repeat: 4910 / 638

On to step 6:
638 goes into 4910 7 times with a remainder of 444.
The number 7 becomes the next digit in our result. 
Result so far: 1417.0
Subtracting 4466 from 4910 leaves us with 444.
Take the next digit (7) from the dividend and append it to 444, then repeat: 4447 / 638

Going ahead to step 7:
When dividing 4447 by 638, we get 6 with a remainder of 619.
The next digit of our result is 6. 
Result so far: 14176.0
Deduct 3828 from 4447 and we're left with 619.
Grab the next digit (2) from the dividend, add it to 619, then carry on: 6192 / 638

Let's proceed to step 8:
The number 638 fits into 6192 9 times, leaving a remainder of 450.
Put 9 as the next digit of the answer. 
Result so far: 141769.0
The remainder is 450 after subtracting 5742 from 6192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 9:
4500 divided by 638 is 7 with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 141769.7
Subtracting 4466 from 4500 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
638 goes into 340 0 times with a remainder of 340.
Put 0 as the next digit of the answer. 
Result so far: 141769.7
Subtract 0 from 340 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 11:
3400 divided by 638 is 5 with a remainder of 210.
Put 5 as the next digit of the answer. 
Result so far: 141769.705
The remainder is 210 after subtracting 3190 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 12:
638 goes into 2100 3 times with a remainder of 186.
Use 3 as the next digit of our solution. 
Result so far: 141769.7053
Subtract 1914 from 2100 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 13:
When dividing 1860 by 638, we get 2 with a remainder of 584.
Write down 2 as next digit of the result. 
Result so far: 141769.70532
Subtract 1276 from 1860 to get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 14:
When dividing 5840 by 638, we get 9 with a remainder of 98.
Use 9 as the next digit of our solution. 
Result so far: 141769.705329
Subtract 5742 from 5840 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 15:
The number 638 fits into 980 1 times, leaving a remainder of 342.
Use 1 as the next digit of our solution. 
Result so far: 141769.7053291
If we take 638 away from 980, we end up with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 16:
3420 divided by 638 is 5 with a remainder of 230.
The next digit of our result is 5. 
Result so far: 141769.70532915
Deduct 3190 from 3420 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Our division results in 141769.70532915 with a remaining 2.3e-07.
