Let's divide 91036606 by 638
We want to figure out the number of times 91036606 can be divided by 638.

Advancing to step 1:
When dividing 9 by 638, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 638

Going ahead to step 2:
638 can be fit into 91 0 times, resulting in a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Include the next digit (0) from the dividend after 91, then repeat: 910 / 638

Let's proceed to step 3:
638 goes into 910 1 times with a remainder of 272.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 638 from 910 leaves us with 272.
Grab the next digit (3) from the dividend, add it to 272, then carry on: 2723 / 638

Advancing to step 4:
638 can be fit into 2723 4 times, resulting in a remainder of 171.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 2552 from 2723, we get 171.
Append the next digit (6) from the dividend to 171 and continue with: 1716 / 638

Going ahead to step 5:
If we divide 1716 by 638, we get 2 and a remainder of 440.
Use 2 as the next digit of our solution. 
Result so far: 142.0
If we subtract 1276 from 1716, we get 440.
Take the next digit (6) from the dividend and append it to 440, then repeat: 4406 / 638

Let's proceed to step 6:
638 goes into 4406 6 times with a remainder of 578.
Write down 6 as next digit of the result. 
Result so far: 1426.0
If we take 3828 away from 4406, we end up with 578.
Grab the next digit (0) from the dividend, add it to 578, then carry on: 5780 / 638

On to step 7:
638 goes into 5780 9 times with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 14269.0
Subtracting 5742 from 5780 leaves us with 38.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 638

Moving on to step 8:
The number 638 fits into 386 0 times, leaving a remainder of 386.
Write down 0 as next digit of the result. 
Result so far: 142690.0
Subtracting 0 from 386 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 9:
3860 divided by 638 is 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 142690.6
If we take 3828 away from 3860, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
If we divide 320 by 638, we get 0 and a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 142690.6
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 11:
If we divide 3200 by 638, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 142690.605
The remainder is 10 after subtracting 3190 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
The number 638 fits into 100 0 times, leaving a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 142690.605
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 13:
638 can be fit into 1000 1 times, resulting in a remainder of 362.
Put 1 as the next digit of the answer. 
Result so far: 142690.60501
If we take 638 away from 1000, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

On to step 14:
3620 divided by 638 is 5 with a remainder of 430.
The number 5 becomes the next digit in our result. 
Result so far: 142690.605015
Subtracting 3190 from 3620 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Let's proceed to step 15:
638 can be fit into 4300 6 times, resulting in a remainder of 472.
Record the quotient 6 as the next digit in the result. 
Result so far: 142690.6050156
Subtract 3828 from 4300 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 16:
The number 638 fits into 4720 7 times, leaving a remainder of 254.
Put 7 as the next digit of the answer. 
Result so far: 142690.60501567
Subtract 4466 from 4720 to get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

The final outcome is 142690.60501567, with a leftover of 2.54e-07.
