Subtract 0 from 7 to get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 661

On to step 2:
The number 661 fits into 75 0 times, leaving a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Fetch the next digit (4) from the dividend, attach it to 75 and continue: 754 / 661

On to step 3:
When dividing 754 by 661, we get 1 with a remainder of 93.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 661 from 754, we get 93.
Fetch the next digit (3) from the dividend, attach it to 93 and continue: 933 / 661

Step 4:
933 divided by 661 is 1 with a remainder of 272.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 661 from 933 and we're left with 272.
Append the next digit (9) from the dividend to 272 and continue with: 2729 / 661

Going ahead to step 5:
2729 divided by 661 is 4 with a remainder of 85.
The next digit of our result is 4. 
Result so far: 114.0
If we subtract 2644 from 2729, we get 85.
Grab the next digit (0) from the dividend, add it to 85, then carry on: 850 / 661

Moving on to step 6:
The number 661 fits into 850 1 times, leaving a remainder of 189.
Put 1 as the next digit of the answer. 
Result so far: 1141.0
The remainder is 189 after subtracting 661 from 850.
Grab the next digit (3) from the dividend, add it to 189, then carry on: 1893 / 661

On to step 7:
If we divide 1893 by 661, we get 2 and a remainder of 571.
Put 2 as the next digit of the answer. 
Result so far: 11412.0
Subtract 1322 from 1893 to get 571.
Fetch the next digit (0) from the dividend, attach it to 571 and continue: 5710 / 661

Let's proceed to step 8:
If we divide 5710 by 661, we get 8 and a remainder of 422.
Write down 8 as next digit of the result. 
Result so far: 114128.0
Subtract 5288 from 5710 to get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

On to step 9:
If we divide 4220 by 661, we get 6 and a remainder of 254.
The next digit of our result is 6. 
Result so far: 114128.6
If we subtract 3966 from 4220, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Step 10:
661 can be fit into 2540 3 times, resulting in a remainder of 557.
Use 3 as the next digit of our solution. 
Result so far: 114128.63
The remainder is 557 after subtracting 1983 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Moving on to step 11:
5570 divided by 661 is 8 with a remainder of 282.
Write down 8 as next digit of the result. 
Result so far: 114128.638
Subtracting 5288 from 5570 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 12:
If we divide 2820 by 661, we get 4 and a remainder of 176.
Record the quotient 4 as the next digit in the result. 
Result so far: 114128.6384
Subtract 2644 from 2820 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 13:
If we divide 1760 by 661, we get 2 and a remainder of 438.
Record the quotient 2 as the next digit in the result. 
Result so far: 114128.63842
If we take 1322 away from 1760, we end up with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Going ahead to step 14:
661 goes into 4380 6 times with a remainder of 414.
Put 6 as the next digit of the answer. 
Result so far: 114128.638426
The remainder is 414 after subtracting 3966 from 4380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 15:
When dividing 4140 by 661, we get 6 with a remainder of 174.
The next digit of our result is 6. 
Result so far: 114128.6384266
If we subtract 3966 from 4140, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

The final outcome is 114128.6384266, with a leftover of 1.74e-06.
