We're dividing 125817 by 49 
We want to figure out the number of times 125817 can be divided by 49.

Step 1:
49 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 49

Going ahead to step 2:
49 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 49

Let's proceed to step 3:
If we divide 125 by 49, we get 2 and a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 98 from 125 and we're left with 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 49

Going ahead to step 4:
278 divided by 49 is 5 with a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Deduct 245 from 278 and we're left with 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 49

On to step 5:
49 can be fit into 331 6 times, resulting in a remainder of 37.
Write down 6 as next digit of the result. 
Result so far: 256.0
The remainder is 37 after subtracting 294 from 331.
Take the next digit (7) from the dividend and append it to 37, then repeat: 377 / 49

On to step 6:
49 goes into 377 7 times with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 2567.0
The remainder is 34 after subtracting 343 from 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
If we divide 340 by 49, we get 6 and a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 2567.6
If we take 294 away from 340, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 8:
460 divided by 49 is 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 2567.69
Deduct 441 from 460 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
190 divided by 49 is 3 with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 2567.693
The remainder is 43 after subtracting 147 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 10:
430 divided by 49 is 8 with a remainder of 38.
The next digit of our result is 8. 
Result so far: 2567.6938
Subtract 392 from 430 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
380 divided by 49 is 7 with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 2567.69387
Deduct 343 from 380 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
When dividing 370 by 49, we get 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 2567.693877
The remainder is 27 after subtracting 343 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final outcome is 2567.693877, with a leftover of 2.7e-06.
