63998283 ÷ 637 
Our goal is to divide 63998283 by 637.

Advancing to step 1:
637 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 637

Moving on to step 2:
When dividing 63 by 637, we get 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 637

On to step 3:
637 goes into 639 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 637 from 639, we get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 637

Advancing to step 4:
If we divide 29 by 637, we get 0 and a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 29 to get 29.
Fetch the next digit (8) from the dividend, attach it to 29 and continue: 298 / 637

Going ahead to step 5:
The number 637 fits into 298 0 times, leaving a remainder of 298.
Put 0 as the next digit of the answer. 
Result so far: 100.0
If we subtract 0 from 298, we get 298.
Take the next digit (2) from the dividend and append it to 298, then repeat: 2982 / 637

On to step 6:
2982 divided by 637 is 4 with a remainder of 434.
The next digit of our result is 4. 
Result so far: 1004.0
Subtract 2548 from 2982 to get 434.
Grab the next digit (8) from the dividend, add it to 434, then carry on: 4348 / 637

Step 7:
If we divide 4348 by 637, we get 6 and a remainder of 526.
Record the quotient 6 as the next digit in the result. 
Result so far: 10046.0
Subtract 3822 from 4348 to get 526.
Take the next digit (3) from the dividend and append it to 526, then repeat: 5263 / 637

Going ahead to step 8:
637 can be fit into 5263 8 times, resulting in a remainder of 167.
Record the quotient 8 as the next digit in the result. 
Result so far: 100468.0
If we take 5096 away from 5263, we end up with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Step 9:
The number 637 fits into 1670 2 times, leaving a remainder of 396.
Write down 2 as next digit of the result. 
Result so far: 100468.2
If we subtract 1274 from 1670, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 10:
When dividing 3960 by 637, we get 6 with a remainder of 138.
Put 6 as the next digit of the answer. 
Result so far: 100468.26
If we take 3822 away from 3960, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 11:
637 can be fit into 1380 2 times, resulting in a remainder of 106.
Use 2 as the next digit of our solution. 
Result so far: 100468.262
Subtracting 1274 from 1380 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 12:
1060 divided by 637 is 1 with a remainder of 423.
Put 1 as the next digit of the answer. 
Result so far: 100468.2621
If we take 637 away from 1060, we end up with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

On to step 13:
637 goes into 4230 6 times with a remainder of 408.
The next digit of our result is 6. 
Result so far: 100468.26216
If we take 3822 away from 4230, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Let's proceed to step 14:
The number 637 fits into 4080 6 times, leaving a remainder of 258.
Use 6 as the next digit of our solution. 
Result so far: 100468.262166
If we subtract 3822 from 4080, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

The final outcome is 100468.262166, with a leftover of 2.58e-05.
