12734141 ÷ 637 
We want to divide 12734141 by 637.

Going ahead to step 1:
When dividing 1 by 637, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 637

Let's proceed to step 2:
637 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 637

Advancing to step 3:
When dividing 127 by 637, we get 0 with a remainder of 127.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 127, we end up with 127.
Grab the next digit (3) from the dividend, add it to 127, then carry on: 1273 / 637

Step 4:
If we divide 1273 by 637, we get 1 and a remainder of 636.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 637 from 1273 and we're left with 636.
Bring next digit (4) of the dividend behind the 636 and repeat the process: 6364 / 637

On to step 5:
When dividing 6364 by 637, we get 9 with a remainder of 631.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 631 after subtracting 5733 from 6364.
Append the next digit (1) from the dividend to 631 and continue with: 6311 / 637

On to step 6:
6311 divided by 637 is 9 with a remainder of 578.
Put 9 as the next digit of the answer. 
Result so far: 199.0
Subtracting 5733 from 6311 leaves us with 578.
Bring next digit (4) of the dividend behind the 578 and repeat the process: 5784 / 637

On to step 7:
The number 637 fits into 5784 9 times, leaving a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 1999.0
Subtract 5733 from 5784 to get 51.
Bring next digit (1) of the dividend behind the 51 and repeat the process: 511 / 637

Going ahead to step 8:
637 can be fit into 511 0 times, resulting in a remainder of 511.
Write down 0 as next digit of the result. 
Result so far: 19990.0
Deduct 0 from 511 and we're left with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Advancing to step 9:
637 goes into 5110 8 times with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 19990.8
Subtracting 5096 from 5110 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
When dividing 140 by 637, we get 0 with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 19990.8
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
The number 637 fits into 1400 2 times, leaving a remainder of 126.
The next digit of our result is 2. 
Result so far: 19990.802
Deduct 1274 from 1400 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 12:
637 goes into 1260 1 times with a remainder of 623.
Use 1 as the next digit of our solution. 
Result so far: 19990.8021
If we subtract 637 from 1260, we get 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Let's proceed to step 13:
If we divide 6230 by 637, we get 9 and a remainder of 497.
Put 9 as the next digit of the answer. 
Result so far: 19990.80219
Subtract 5733 from 6230 to get 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Going ahead to step 14:
If we divide 4970 by 637, we get 7 and a remainder of 511.
The next digit of our result is 7. 
Result so far: 19990.802197
The remainder is 511 after subtracting 4459 from 4970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Going ahead to step 15:
If we divide 5110 by 637, we get 8 and a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 19990.8021978
If we take 5096 away from 5110, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 16:
When dividing 140 by 637, we get 0 with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 19990.8021978
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final outcome is 19990.8021978, with a leftover of 1.4e-07.
