89210349 divided by 638 
Let's see how many times 638 fits into 89210349.

Let's proceed to step 1:
When dividing 8 by 638, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 638

Going ahead to step 2:
89 divided by 638 is 0 with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Include the next digit (2) from the dividend after 89, then repeat: 892 / 638

Moving on to step 3:
The number 638 fits into 892 1 times, leaving a remainder of 254.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 638 from 892, we get 254.
Grab the next digit (1) from the dividend, add it to 254, then carry on: 2541 / 638

Advancing to step 4:
638 can be fit into 2541 3 times, resulting in a remainder of 627.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 1914 from 2541, we get 627.
Bring next digit (0) of the dividend behind the 627 and repeat the process: 6270 / 638

Going ahead to step 5:
The number 638 fits into 6270 9 times, leaving a remainder of 528.
Use 9 as the next digit of our solution. 
Result so far: 139.0
If we take 5742 away from 6270, we end up with 528.
Take the next digit (3) from the dividend and append it to 528, then repeat: 5283 / 638

Step 6:
If we divide 5283 by 638, we get 8 and a remainder of 179.
The number 8 becomes the next digit in our result. 
Result so far: 1398.0
Subtract 5104 from 5283 to get 179.
Grab the next digit (4) from the dividend, add it to 179, then carry on: 1794 / 638

Moving on to step 7:
The number 638 fits into 1794 2 times, leaving a remainder of 518.
The number 2 becomes the next digit in our result. 
Result so far: 13982.0
Subtract 1276 from 1794 to get 518.
Bring next digit (9) of the dividend behind the 518 and repeat the process: 5189 / 638

Advancing to step 8:
638 can be fit into 5189 8 times, resulting in a remainder of 85.
Write down 8 as next digit of the result. 
Result so far: 139828.0
If we subtract 5104 from 5189, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 9:
When dividing 850 by 638, we get 1 with a remainder of 212.
Put 1 as the next digit of the answer. 
Result so far: 139828.1
The remainder is 212 after subtracting 638 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 10:
638 can be fit into 2120 3 times, resulting in a remainder of 206.
Put 3 as the next digit of the answer. 
Result so far: 139828.13
Deduct 1914 from 2120 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 11:
638 goes into 2060 3 times with a remainder of 146.
Record the quotient 3 as the next digit in the result. 
Result so far: 139828.133
The remainder is 146 after subtracting 1914 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

The quotient of the division is 139828.133, and the remainder is 0.0146.
