We look at the division of 661870 by 61 
Our goal is to divide 661870 by 61.

Going ahead to step 1:
61 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 61

Moving on to step 2:
66 divided by 61 is 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 5 after subtracting 61 from 66.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 61

Advancing to step 3:
51 divided by 61 is 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 51 to get 51.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 61

Advancing to step 4:
61 can be fit into 518 8 times, resulting in a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 108.0
If we take 488 away from 518, we end up with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 61

Moving on to step 5:
61 can be fit into 307 5 times, resulting in a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 1085.0
Deduct 305 from 307 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 61

Moving on to step 6:
20 divided by 61 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 10850.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
200 divided by 61 is 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 10850.3
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.

Advancing to step 8:
170 divided by 61 is 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 10850.32
Subtract 122 from 170 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
If we divide 480 by 61, we get 7 and a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 10850.327
If we subtract 427 from 480, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 10:
When dividing 530 by 61, we get 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 10850.3278
Deduct 488 from 530 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
420 divided by 61 is 6 with a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 10850.32786
Subtracting 366 from 420 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 12:
The number 61 fits into 540 8 times, leaving a remainder of 52.
The next digit of our result is 8. 
Result so far: 10850.327868
Subtracting 488 from 540 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 13:
520 divided by 61 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 10850.3278688
Subtract 488 from 520 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 10850.3278688, and the remainder is 3.2e-07.
