We divide 644121 by 49
We want to figure out the number of times 644121 can be divided by 49.

Moving on to step 1:
When dividing 6 by 49, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 49

Moving on to step 2:
The number 49 fits into 64 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 49 from 64 leaves us with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 49

On to step 3:
The number 49 fits into 154 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 147 from 154, we get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 49

Step 4:
The number 49 fits into 71 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 131.0
Subtract 49 from 71 to get 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 49

Going ahead to step 5:
222 divided by 49 is 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 1314.0
If we take 196 away from 222, we end up with 26.
Fetch the next digit (1) from the dividend, attach it to 26 and continue: 261 / 49

Step 6:
49 goes into 261 5 times with a remainder of 16.
The next digit of our result is 5. 
Result so far: 13145.0
Deduct 245 from 261 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
The number 49 fits into 160 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 13145.3
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
130 divided by 49 is 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 13145.32
If we subtract 98 from 130, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
When dividing 320 by 49, we get 6 with a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 13145.326
If we take 294 away from 320, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
The number 49 fits into 260 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 13145.3265
Subtracting 245 from 260 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
49 goes into 150 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 13145.32653
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
The number 49 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 13145.32653
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
49 goes into 300 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 13145.3265306
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
If we divide 60 by 49, we get 1 and a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 13145.32653061
If we subtract 49 from 60, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 13145.32653061 and a remainder of 1.1e-08.
