1948505 ÷ 661 
Our goal is to divide 1948505 by 661.

Step 1:
661 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 661

Going ahead to step 2:
When dividing 19 by 661, we get 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 661

Step 3:
194 divided by 661 is 0 with a remainder of 194.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 194 after subtracting 0 from 194.
Take the next digit (8) from the dividend and append it to 194, then repeat: 1948 / 661

On to step 4:
If we divide 1948 by 661, we get 2 and a remainder of 626.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 626 after subtracting 1322 from 1948.
Bring next digit (5) of the dividend behind the 626 and repeat the process: 6265 / 661

Advancing to step 5:
If we divide 6265 by 661, we get 9 and a remainder of 316.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Deduct 5949 from 6265 and we're left with 316.
Include the next digit (0) from the dividend after 316, then repeat: 3160 / 661

Let's proceed to step 6:
3160 divided by 661 is 4 with a remainder of 516.
Use 4 as the next digit of our solution. 
Result so far: 294.0
The remainder is 516 after subtracting 2644 from 3160.
Include the next digit (5) from the dividend after 516, then repeat: 5165 / 661

Let's proceed to step 7:
661 goes into 5165 7 times with a remainder of 538.
The next digit of our result is 7. 
Result so far: 2947.0
Subtract 4627 from 5165 to get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Going ahead to step 8:
The number 661 fits into 5380 8 times, leaving a remainder of 92.
Write down 8 as next digit of the result. 
Result so far: 2947.8
Deduct 5288 from 5380 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 9:
When dividing 920 by 661, we get 1 with a remainder of 259.
Put 1 as the next digit of the answer. 
Result so far: 2947.81
Subtract 661 from 920 to get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 10:
If we divide 2590 by 661, we get 3 and a remainder of 607.
Record the quotient 3 as the next digit in the result. 
Result so far: 2947.813
The remainder is 607 after subtracting 1983 from 2590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

On to step 11:
6070 divided by 661 is 9 with a remainder of 121.
Put 9 as the next digit of the answer. 
Result so far: 2947.8139
Subtracting 5949 from 6070 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 12:
661 goes into 1210 1 times with a remainder of 549.
Put 1 as the next digit of the answer. 
Result so far: 2947.81391
The remainder is 549 after subtracting 661 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Moving on to step 13:
5490 divided by 661 is 8 with a remainder of 202.
The next digit of our result is 8. 
Result so far: 2947.813918
Subtracting 5288 from 5490 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 14:
The number 661 fits into 2020 3 times, leaving a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 2947.8139183
Subtract 1983 from 2020 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 15:
370 divided by 661 is 0 with a remainder of 370.
Record the quotient 0 as the next digit in the result. 
Result so far: 2947.8139183
Subtract 0 from 370 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

The final result is 2947.8139183 with a remainder of 3.7e-07.
