We're dividing 646072 by 49 
We want to figure out the number of times 646072 can be divided by 49.

Step 1:
49 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 49

Advancing to step 2:
64 divided by 49 is 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 15 after subtracting 49 from 64.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 49

Step 3:
156 divided by 49 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 147 from 156 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 49

Let's proceed to step 4:
If we divide 90 by 49, we get 1 and a remainder of 41.
The next digit of our result is 1. 
Result so far: 131.0
If we subtract 49 from 90, we get 41.
Take the next digit (7) from the dividend and append it to 41, then repeat: 417 / 49

Step 5:
49 goes into 417 8 times with a remainder of 25.
The number 8 becomes the next digit in our result. 
Result so far: 1318.0
Subtract 392 from 417 to get 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 49

Step 6:
When dividing 252 by 49, we get 5 with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 13185.0
Subtract 245 from 252 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
49 goes into 70 1 times with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 13185.1
If we take 49 away from 70, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 8:
49 can be fit into 210 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 13185.14
Subtract 196 from 210 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
The number 49 fits into 140 2 times, leaving a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 13185.142
Subtracting 98 from 140 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
When dividing 420 by 49, we get 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 13185.1428
Deduct 392 from 420 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
When dividing 280 by 49, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 13185.14285
Subtracting 245 from 280 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
350 divided by 49 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 13185.142857
Deduct 343 from 350 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
When dividing 70 by 49, we get 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 13185.1428571
Deduct 49 from 70 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 14:
49 goes into 210 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 13185.14285714
Subtract 196 from 210 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 13185.14285714 with a remaining 1.4e-08.
