644149 ÷ 61 
We want to figure out the number of times 644149 can be divided by 61.

Let's proceed to step 1:
61 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
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 61

On to step 2:
The number 61 fits into 64 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 61 away from 64, we end up with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 61

Going ahead to step 3:
61 can be fit into 34 0 times, resulting in a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 34 and we're left with 34.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 61

Step 4:
61 can be fit into 341 5 times, resulting in a remainder of 36.
Write down 5 as next digit of the result. 
Result so far: 105.0
If we take 305 away from 341, we end up with 36.
Grab the next digit (4) from the dividend, add it to 36, then carry on: 364 / 61

Moving on to step 5:
When dividing 364 by 61, we get 5 with a remainder of 59.
Use 5 as the next digit of our solution. 
Result so far: 1055.0
Subtract 305 from 364 to get 59.
Grab the next digit (9) from the dividend, add it to 59, then carry on: 599 / 61

Let's proceed to step 6:
When dividing 599 by 61, we get 9 with a remainder of 50.
Put 9 as the next digit of the answer. 
Result so far: 10559.0
Subtracting 549 from 599 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
61 goes into 500 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 10559.8
If we subtract 488 from 500, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
When dividing 120 by 61, we get 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 10559.81
Subtracting 61 from 120 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 9:
590 divided by 61 is 9 with a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 10559.819
Deduct 549 from 590 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 10:
410 divided by 61 is 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 10559.8196
Subtract 366 from 410 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
440 divided by 61 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 10559.81967
Subtracting 427 from 440 leaves us 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.

Going ahead to step 12:
130 divided by 61 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 10559.819672
If we take 122 away from 130, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
61 can be fit into 80 1 times, resulting in a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 10559.8196721
Subtract 61 from 80 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 14:
When dividing 190 by 61, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 10559.81967213
If we subtract 183 from 190, we 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.

The final result is 10559.81967213 with a remainder of 7e-09.
