We look at the division of 877890 by 61 
We want to divide 877890 by 61.

Advancing to step 1:
The number 61 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 61

Going ahead to step 2:
When dividing 87 by 61, we get 1 with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 61 from 87 to get 26.
Grab the next digit (7) from the dividend, add it to 26, then carry on: 267 / 61

On to step 3:
267 divided by 61 is 4 with a remainder of 23.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 244 from 267 leaves us with 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 61

Going ahead to step 4:
When dividing 238 by 61, we get 3 with a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 143.0
The remainder is 55 after subtracting 183 from 238.
Include the next digit (9) from the dividend after 55, then repeat: 559 / 61

On to step 5:
559 divided by 61 is 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 1439.0
The remainder is 10 after subtracting 549 from 559.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 61

On to step 6:
If we divide 100 by 61, we get 1 and a remainder of 39.
The next digit of our result is 1. 
Result so far: 14391.0
Deduct 61 from 100 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
61 can be fit into 390 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 14391.6
If we take 366 away from 390, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
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: 14391.63
Deduct 183 from 240 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 9:
When dividing 570 by 61, we get 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 14391.639
If we subtract 549 from 570, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 10:
61 goes into 210 3 times with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 14391.6393
If we subtract 183 from 210, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 11:
61 goes into 270 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 14391.63934
If we take 244 away from 270, 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.

Step 12:
260 divided by 61 is 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 14391.639344
If we subtract 244 from 260, we 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 14391.639344, with a leftover of 1.6e-06.
