91496564 ÷ 631 
Our goal is to divide 91496564 by 631.

Let's proceed to step 1:
When dividing 9 by 631, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 631

Step 2:
The number 631 fits into 91 0 times, leaving a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Append the next digit (4) from the dividend to 91 and continue with: 914 / 631

Going ahead to step 3:
The number 631 fits into 914 1 times, leaving a remainder of 283.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 631 from 914 to get 283.
Fetch the next digit (9) from the dividend, attach it to 283 and continue: 2839 / 631

Going ahead to step 4:
631 goes into 2839 4 times with a remainder of 315.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 2524 from 2839 to get 315.
Include the next digit (6) from the dividend after 315, then repeat: 3156 / 631

On to step 5:
When dividing 3156 by 631, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 145.0
Subtracting 3155 from 3156 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 631

Let's proceed to step 6:
631 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 1450.0
If we take 0 away from 15, we end up with 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 631

Let's proceed to step 7:
631 can be fit into 156 0 times, resulting in a remainder of 156.
The next digit of our result is 0. 
Result so far: 14500.0
Deduct 0 from 156 and we're left with 156.
Take the next digit (4) from the dividend and append it to 156, then repeat: 1564 / 631

On to step 8:
The number 631 fits into 1564 2 times, leaving a remainder of 302.
The number 2 becomes the next digit in our result. 
Result so far: 145002.0
If we take 1262 away from 1564, we end up with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 9:
3020 divided by 631 is 4 with a remainder of 496.
The number 4 becomes the next digit in our result. 
Result so far: 145002.4
Subtract 2524 from 3020 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Going ahead to step 10:
631 can be fit into 4960 7 times, resulting in a remainder of 543.
The number 7 becomes the next digit in our result. 
Result so far: 145002.47
Subtracting 4417 from 4960 leaves us with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Step 11:
If we divide 5430 by 631, we get 8 and a remainder of 382.
The next digit of our result is 8. 
Result so far: 145002.478
Subtract 5048 from 5430 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 12:
3820 divided by 631 is 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 145002.4786
If we subtract 3786 from 3820, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
340 divided by 631 is 0 with a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 145002.4786
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 14:
When dividing 3400 by 631, we get 5 with a remainder of 245.
Use 5 as the next digit of our solution. 
Result so far: 145002.478605
The remainder is 245 after subtracting 3155 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Advancing to step 15:
631 goes into 2450 3 times with a remainder of 557.
Use 3 as the next digit of our solution. 
Result so far: 145002.4786053
If we take 1893 away from 2450, we end up with 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Going ahead to step 16:
631 goes into 5570 8 times with a remainder of 522.
The number 8 becomes the next digit in our result. 
Result so far: 145002.47860538
Subtract 5048 from 5570 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

After the division, we end up with 145002.47860538 and a remainder of 5.22e-07.
