We're dividing 90628639 by 635 
We want to figure out the number of times 90628639 can be divided by 635.

Let's proceed to step 1:
The number 635 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 635

Advancing to step 2:
The number 635 fits into 90 0 times, leaving a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Include the next digit (6) from the dividend after 90, then repeat: 906 / 635

Advancing to step 3:
635 can be fit into 906 1 times, resulting in a remainder of 271.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 635 away from 906, we end up with 271.
Take the next digit (2) from the dividend and append it to 271, then repeat: 2712 / 635

Step 4:
2712 divided by 635 is 4 with a remainder of 172.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 2540 from 2712 to get 172.
Include the next digit (8) from the dividend after 172, then repeat: 1728 / 635

Advancing to step 5:
If we divide 1728 by 635, we get 2 and a remainder of 458.
Write down 2 as next digit of the result. 
Result so far: 142.0
Deduct 1270 from 1728 and we're left with 458.
Append the next digit (6) from the dividend to 458 and continue with: 4586 / 635

Going ahead to step 6:
If we divide 4586 by 635, we get 7 and a remainder of 141.
The next digit of our result is 7. 
Result so far: 1427.0
Subtract 4445 from 4586 to get 141.
Grab the next digit (3) from the dividend, add it to 141, then carry on: 1413 / 635

Advancing to step 7:
The number 635 fits into 1413 2 times, leaving a remainder of 143.
The number 2 becomes the next digit in our result. 
Result so far: 14272.0
Subtracting 1270 from 1413 leaves us with 143.
Grab the next digit (9) from the dividend, add it to 143, then carry on: 1439 / 635

Advancing to step 8:
When dividing 1439 by 635, we get 2 with a remainder of 169.
Record the quotient 2 as the next digit in the result. 
Result so far: 142722.0
Subtract 1270 from 1439 to get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

On to step 9:
The number 635 fits into 1690 2 times, leaving a remainder of 420.
The next digit of our result is 2. 
Result so far: 142722.2
Deduct 1270 from 1690 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 10:
If we divide 4200 by 635, we get 6 and a remainder of 390.
Record the quotient 6 as the next digit in the result. 
Result so far: 142722.26
Deduct 3810 from 4200 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 11:
When dividing 3900 by 635, we get 6 with a remainder of 90.
The number 6 becomes the next digit in our result. 
Result so far: 142722.266
Deduct 3810 from 3900 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

In conclusion, the division gives 142722.266 with a balance of 0.009.
