661554 ÷ 49 
Let's see how many times 49 fits into 661554.

Going ahead to step 1:
If we divide 6 by 49, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 49

Advancing to step 2:
49 can be fit into 66 1 times, resulting in a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 49 from 66 to get 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 49

Advancing to step 3:
If we divide 171 by 49, we get 3 and a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 147 from 171 to get 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 49

Advancing to step 4:
49 can be fit into 245 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 135.0
Deduct 245 from 245 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 49

Let's proceed to step 5:
49 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 1350.0
If we subtract 0 from 5, we get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 49

On to step 6:
49 goes into 54 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 13501.0
Deduct 49 from 54 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
49 can be fit into 50 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 13501.1
If we subtract 49 from 50, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
If we divide 10 by 49, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 13501.1
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
When dividing 100 by 49, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 13501.102
If we subtract 98 from 100, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
49 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 13501.102
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.

Step 11:
49 can be fit into 200 4 times, resulting in a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 13501.10204
If we subtract 196 from 200, we get 4.
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 12:
When dividing 40 by 49, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 13501.10204
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.

Advancing to step 13:
When dividing 400 by 49, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 13501.1020408
Subtracting 392 from 400 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
When dividing 80 by 49, we get 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 13501.10204081
Deduct 49 from 80 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

After the division, we end up with 13501.10204081 and a remainder of 3.1e-08.
