We're dividing 61437664 by 873 
Let's see how many times 873 fits into 61437664.

Going ahead to step 1:
When dividing 6 by 873, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 873

Moving on to step 2:
If we divide 61 by 873, we get 0 and a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Include the next digit (4) from the dividend after 61, then repeat: 614 / 873

Let's proceed to step 3:
873 can be fit into 614 0 times, resulting in a remainder of 614.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 614, we get 614.
Bring next digit (3) of the dividend behind the 614 and repeat the process: 6143 / 873

Advancing to step 4:
If we divide 6143 by 873, we get 7 and a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 6111 from 6143, we get 32.
Append the next digit (7) from the dividend to 32 and continue with: 327 / 873

Step 5:
327 divided by 873 is 0 with a remainder of 327.
Put 0 as the next digit of the answer. 
Result so far: 70.0
Deduct 0 from 327 and we're left with 327.
Include the next digit (6) from the dividend after 327, then repeat: 3276 / 873

Advancing to step 6:
873 can be fit into 3276 3 times, resulting in a remainder of 657.
The next digit of our result is 3. 
Result so far: 703.0
Subtract 2619 from 3276 to get 657.
Include the next digit (6) from the dividend after 657, then repeat: 6576 / 873

Going ahead to step 7:
6576 divided by 873 is 7 with a remainder of 465.
The number 7 becomes the next digit in our result. 
Result so far: 7037.0
Subtract 6111 from 6576 to get 465.
Grab the next digit (4) from the dividend, add it to 465, then carry on: 4654 / 873

Advancing to step 8:
The number 873 fits into 4654 5 times, leaving a remainder of 289.
Write down 5 as next digit of the result. 
Result so far: 70375.0
Subtract 4365 from 4654 to get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Going ahead to step 9:
873 can be fit into 2890 3 times, resulting in a remainder of 271.
The next digit of our result is 3. 
Result so far: 70375.3
If we take 2619 away from 2890, we end up with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Moving on to step 10:
When dividing 2710 by 873, we get 3 with a remainder of 91.
Write down 3 as next digit of the result. 
Result so far: 70375.33
If we subtract 2619 from 2710, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

After the division, we end up with 70375.33 and a remainder of 0.091.
