83691607 ÷ 637 
Let's see how many times 637 fits into 83691607.

Advancing to step 1:
The number 637 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 637

Let's proceed to step 2:
When dividing 83 by 637, we get 0 with a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Bring next digit (6) of the dividend behind the 83 and repeat the process: 836 / 637

On to step 3:
637 goes into 836 1 times with a remainder of 199.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 637 from 836 leaves us with 199.
Take the next digit (9) from the dividend and append it to 199, then repeat: 1999 / 637

Going ahead to step 4:
637 goes into 1999 3 times with a remainder of 88.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1911 from 1999 leaves us with 88.
Take the next digit (1) from the dividend and append it to 88, then repeat: 881 / 637

Moving on to step 5:
881 divided by 637 is 1 with a remainder of 244.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
The remainder is 244 after subtracting 637 from 881.
Bring next digit (6) of the dividend behind the 244 and repeat the process: 2446 / 637

Let's proceed to step 6:
When dividing 2446 by 637, we get 3 with a remainder of 535.
The next digit of our result is 3. 
Result so far: 1313.0
The remainder is 535 after subtracting 1911 from 2446.
Append the next digit (0) from the dividend to 535 and continue with: 5350 / 637

Let's proceed to step 7:
5350 divided by 637 is 8 with a remainder of 254.
Use 8 as the next digit of our solution. 
Result so far: 13138.0
If we take 5096 away from 5350, we end up with 254.
Bring next digit (7) of the dividend behind the 254 and repeat the process: 2547 / 637

Let's proceed to step 8:
When dividing 2547 by 637, we get 3 with a remainder of 636.
Use 3 as the next digit of our solution. 
Result so far: 131383.0
Subtracting 1911 from 2547 leaves us with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Going ahead to step 9:
6360 divided by 637 is 9 with a remainder of 627.
Put 9 as the next digit of the answer. 
Result so far: 131383.9
Deduct 5733 from 6360 and we're left with 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Let's proceed to step 10:
637 can be fit into 6270 9 times, resulting in a remainder of 537.
Use 9 as the next digit of our solution. 
Result so far: 131383.99
The remainder is 537 after subtracting 5733 from 6270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

The final result is 131383.99 with a remainder of 0.537.
