Let's divide 815621 by 61
Let's see how many times 61 fits into 815621.

On to step 1:
The number 61 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 61

On to step 2:
When dividing 81 by 61, we get 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 61 from 81, we get 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 61

Let's proceed to step 3:
When dividing 205 by 61, we get 3 with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 183 from 205 to get 22.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 61

Let's proceed to step 4:
If we divide 226 by 61, we get 3 and a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 133.0
Subtract 183 from 226 to get 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 61

On to step 5:
The number 61 fits into 432 7 times, leaving a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 1337.0
Subtract 427 from 432 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 61

Let's proceed to step 6:
51 divided by 61 is 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 13370.0
Subtract 0 from 51 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
61 can be fit into 510 8 times, resulting in a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 13370.8
Subtracting 488 from 510 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
When dividing 220 by 61, we get 3 with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 13370.83
Subtracting 183 from 220 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
When dividing 370 by 61, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 13370.836
The remainder is 4 after subtracting 366 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
61 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 13370.836
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
When dividing 400 by 61, we get 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 13370.83606
Subtract 366 from 400 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
The number 61 fits into 340 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 13370.836065
Deduct 305 from 340 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 13:
350 divided by 61 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 13370.8360655
If we subtract 305 from 350, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The quotient of the division is 13370.8360655, and the remainder is 4.5e-07.
