We look at the division of 8155092 by 637 
Our goal is to divide 8155092 by 637.

On to step 1:
The number 637 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 637

Step 2:
The number 637 fits into 81 0 times, leaving a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Take the next digit (5) from the dividend and append it to 81, then repeat: 815 / 637

Let's proceed to step 3:
815 divided by 637 is 1 with a remainder of 178.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 637 from 815 to get 178.
Include the next digit (5) from the dividend after 178, then repeat: 1785 / 637

On to step 4:
1785 divided by 637 is 2 with a remainder of 511.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 511 after subtracting 1274 from 1785.
Include the next digit (0) from the dividend after 511, then repeat: 5110 / 637

Advancing to step 5:
637 can be fit into 5110 8 times, resulting in a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 128.0
Subtracting 5096 from 5110 leaves us with 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 637

Moving on to step 6:
When dividing 149 by 637, we get 0 with a remainder of 149.
The number 0 becomes the next digit in our result. 
Result so far: 1280.0
If we take 0 away from 149, we end up with 149.
Grab the next digit (2) from the dividend, add it to 149, then carry on: 1492 / 637

Step 7:
637 goes into 1492 2 times with a remainder of 218.
Record the quotient 2 as the next digit in the result. 
Result so far: 12802.0
If we take 1274 away from 1492, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 8:
637 can be fit into 2180 3 times, resulting in a remainder of 269.
The next digit of our result is 3. 
Result so far: 12802.3
Deduct 1911 from 2180 and we're left with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Advancing to step 9:
637 can be fit into 2690 4 times, resulting in a remainder of 142.
Use 4 as the next digit of our solution. 
Result so far: 12802.34
Subtracting 2548 from 2690 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 10:
637 can be fit into 1420 2 times, resulting in a remainder of 146.
Put 2 as the next digit of the answer. 
Result so far: 12802.342
Subtract 1274 from 1420 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 11:
637 can be fit into 1460 2 times, resulting in a remainder of 186.
The next digit of our result is 2. 
Result so far: 12802.3422
The remainder is 186 after subtracting 1274 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

The final outcome is 12802.3422, with a leftover of 0.00186.
