We look at the division of 864441 by 61 
We're looking to find how many times 61 goes into 864441.

Going ahead to step 1:
61 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 61

Moving on to step 2:
61 can be fit into 86 1 times, resulting in a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 61 from 86 to get 25.
Grab the next digit (4) from the dividend, add it to 25, then carry on: 254 / 61

Advancing to step 3:
61 can be fit into 254 4 times, resulting in a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 244 from 254, we get 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 61

On to step 4:
The number 61 fits into 104 1 times, leaving a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 141.0
Deduct 61 from 104 and we're left with 43.
Bring next digit (4) of the dividend behind the 43 and repeat the process: 434 / 61

Step 5:
If we divide 434 by 61, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 1417.0
Subtracting 427 from 434 leaves us with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 61

On to step 6:
61 can be fit into 71 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 14171.0
Deduct 61 from 71 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
When dividing 100 by 61, we get 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 14171.1
Subtract 61 from 100 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 8:
When dividing 390 by 61, we get 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 14171.16
The remainder is 24 after subtracting 366 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
The number 61 fits into 240 3 times, leaving a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 14171.163
Subtract 183 from 240 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 10:
If we divide 570 by 61, we get 9 and a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 14171.1639
Subtracting 549 from 570 leaves us 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 11:
The number 61 fits into 210 3 times, leaving a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 14171.16393
Deduct 183 from 210 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 12:
61 goes into 270 4 times with a remainder of 26.
The next digit of our result is 4. 
Result so far: 14171.163934
Deduct 244 from 270 and we're left 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.

On to step 13:
260 divided by 61 is 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 14171.1639344
Subtract 244 from 260 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 14171.1639344, with a leftover of 1.6e-07.
