85172960 ÷ 637 
We want to figure out the number of times 85172960 can be divided by 637.

On to step 1:
8 divided by 637 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 637

On to step 2:
85 divided by 637 is 0 with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Fetch the next digit (1) from the dividend, attach it to 85 and continue: 851 / 637

Let's proceed to step 3:
637 goes into 851 1 times with a remainder of 214.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 637 from 851 to get 214.
Append the next digit (7) from the dividend to 214 and continue with: 2147 / 637

Step 4:
637 can be fit into 2147 3 times, resulting in a remainder of 236.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1911 from 2147 to get 236.
Take the next digit (2) from the dividend and append it to 236, then repeat: 2362 / 637

Advancing to step 5:
637 goes into 2362 3 times with a remainder of 451.
Put 3 as the next digit of the answer. 
Result so far: 133.0
If we take 1911 away from 2362, we end up with 451.
Include the next digit (9) from the dividend after 451, then repeat: 4519 / 637

Going ahead to step 6:
4519 divided by 637 is 7 with a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 1337.0
If we take 4459 away from 4519, we end up with 60.
Fetch the next digit (6) from the dividend, attach it to 60 and continue: 606 / 637

Moving on to step 7:
When dividing 606 by 637, we get 0 with a remainder of 606.
The number 0 becomes the next digit in our result. 
Result so far: 13370.0
If we take 0 away from 606, we end up with 606.
Grab the next digit (0) from the dividend, add it to 606, then carry on: 6060 / 637

Moving on to step 8:
637 can be fit into 6060 9 times, resulting in a remainder of 327.
The next digit of our result is 9. 
Result so far: 133709.0
Subtracting 5733 from 6060 leaves us with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Step 9:
637 goes into 3270 5 times with a remainder of 85.
The next digit of our result is 5. 
Result so far: 133709.5
If we take 3185 away from 3270, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 10:
637 goes into 850 1 times with a remainder of 213.
The number 1 becomes the next digit in our result. 
Result so far: 133709.51
The remainder is 213 after subtracting 637 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Step 11:
637 can be fit into 2130 3 times, resulting in a remainder of 219.
The next digit of our result is 3. 
Result so far: 133709.513
If we subtract 1911 from 2130, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

On to step 12:
The number 637 fits into 2190 3 times, leaving a remainder of 279.
The next digit of our result is 3. 
Result so far: 133709.5133
Subtract 1911 from 2190 to get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

After the division, we end up with 133709.5133 and a remainder of 0.00279.
