Let's divide 15512115 by 661
Our goal is to divide 15512115 by 661.

Let's proceed to step 1:
When dividing 1 by 661, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 661

Moving on to step 2:
661 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 661

Going ahead to step 3:
The number 661 fits into 155 0 times, leaving a remainder of 155.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 155 after subtracting 0 from 155.
Fetch the next digit (1) from the dividend, attach it to 155 and continue: 1551 / 661

Step 4:
If we divide 1551 by 661, we get 2 and a remainder of 229.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1322 from 1551 leaves us with 229.
Include the next digit (2) from the dividend after 229, then repeat: 2292 / 661

Advancing to step 5:
When dividing 2292 by 661, we get 3 with a remainder of 309.
Use 3 as the next digit of our solution. 
Result so far: 23.0
The remainder is 309 after subtracting 1983 from 2292.
Fetch the next digit (1) from the dividend, attach it to 309 and continue: 3091 / 661

Let's proceed to step 6:
661 can be fit into 3091 4 times, resulting in a remainder of 447.
Put 4 as the next digit of the answer. 
Result so far: 234.0
Subtract 2644 from 3091 to get 447.
Include the next digit (1) from the dividend after 447, then repeat: 4471 / 661

On to step 7:
When dividing 4471 by 661, we get 6 with a remainder of 505.
Record the quotient 6 as the next digit in the result. 
Result so far: 2346.0
Subtracting 3966 from 4471 leaves us with 505.
Fetch the next digit (5) from the dividend, attach it to 505 and continue: 5055 / 661

Let's proceed to step 8:
5055 divided by 661 is 7 with a remainder of 428.
The number 7 becomes the next digit in our result. 
Result so far: 23467.0
Subtract 4627 from 5055 to get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Step 9:
4280 divided by 661 is 6 with a remainder of 314.
Put 6 as the next digit of the answer. 
Result so far: 23467.6
Deduct 3966 from 4280 and we're left with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 10:
If we divide 3140 by 661, we get 4 and a remainder of 496.
Record the quotient 4 as the next digit in the result. 
Result so far: 23467.64
If we take 2644 away from 3140, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 11:
4960 divided by 661 is 7 with a remainder of 333.
Record the quotient 7 as the next digit in the result. 
Result so far: 23467.647
Deduct 4627 from 4960 and we're left with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

On to step 12:
3330 divided by 661 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 23467.6475
Subtracting 3305 from 3330 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
When dividing 250 by 661, we get 0 with a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 23467.6475
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 14:
When dividing 2500 by 661, we get 3 with a remainder of 517.
Write down 3 as next digit of the result. 
Result so far: 23467.647503
Subtract 1983 from 2500 to get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Moving on to step 15:
If we divide 5170 by 661, we get 7 and a remainder of 543.
Record the quotient 7 as the next digit in the result. 
Result so far: 23467.6475037
Deduct 4627 from 5170 and we're left with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Going ahead to step 16:
The number 661 fits into 5430 8 times, leaving a remainder of 142.
Put 8 as the next digit of the answer. 
Result so far: 23467.64750378
Subtracting 5288 from 5430 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Our division results in 23467.64750378 with a remaining 1.42e-07.
