We look at the division of 878403 by 61 
We're looking to find how many times 61 goes into 878403.

Advancing to step 1:
61 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 61

Advancing to step 2:
61 goes into 87 1 times with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 61 from 87 to get 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 61

Step 3:
If we divide 268 by 61, we get 4 and a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 244 away from 268, we end up with 24.
Take the next digit (4) from the dividend and append it to 24, then repeat: 244 / 61

Advancing to step 4:
61 goes into 244 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 144.0
Subtract 244 from 244 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 61

Going ahead to step 5:
61 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1440.0
If we take 0 away from 0, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 61

Advancing to step 6:
3 divided by 61 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 14400.0
If we take 0 away from 3, we end up 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.

Let's proceed to step 7:
When dividing 30 by 61, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 14400.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
When dividing 300 by 61, we get 4 with a remainder of 56.
The next digit of our result is 4. 
Result so far: 14400.04
If we take 244 away from 300, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
The number 61 fits into 560 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 14400.049
Deduct 549 from 560 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 10:
110 divided by 61 is 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 14400.0491
Deduct 61 from 110 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 11:
The number 61 fits into 490 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 14400.04918
Subtracting 488 from 490 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
If we divide 20 by 61, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 14400.04918
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
When dividing 200 by 61, we get 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 14400.0491803
If we take 183 away from 200, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 14:
When dividing 170 by 61, we get 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 14400.04918032
The remainder is 48 after subtracting 122 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 14400.04918032, with a leftover of 4.8e-08.
