We look at the division of 17434678 by 661 
We want to divide 17434678 by 661.

Let's proceed to step 1:
1 divided by 661 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 661

Let's proceed to step 2:
661 goes into 17 0 times with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 661

Step 3:
174 divided by 661 is 0 with a remainder of 174.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 174 and we're left with 174.
Include the next digit (3) from the dividend after 174, then repeat: 1743 / 661

Step 4:
If we divide 1743 by 661, we get 2 and a remainder of 421.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1322 from 1743 and we're left with 421.
Bring next digit (4) of the dividend behind the 421 and repeat the process: 4214 / 661

Moving on to step 5:
When dividing 4214 by 661, we get 6 with a remainder of 248.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
The remainder is 248 after subtracting 3966 from 4214.
Append the next digit (6) from the dividend to 248 and continue with: 2486 / 661

Moving on to step 6:
2486 divided by 661 is 3 with a remainder of 503.
The next digit of our result is 3. 
Result so far: 263.0
Deduct 1983 from 2486 and we're left with 503.
Take the next digit (7) from the dividend and append it to 503, then repeat: 5037 / 661

On to step 7:
When dividing 5037 by 661, we get 7 with a remainder of 410.
Record the quotient 7 as the next digit in the result. 
Result so far: 2637.0
Subtracting 4627 from 5037 leaves us with 410.
Append the next digit (8) from the dividend to 410 and continue with: 4108 / 661

Let's proceed to step 8:
661 goes into 4108 6 times with a remainder of 142.
Write down 6 as next digit of the result. 
Result so far: 26376.0
Subtracting 3966 from 4108 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.

Going ahead to step 9:
When dividing 1420 by 661, we get 2 with a remainder of 98.
The number 2 becomes the next digit in our result. 
Result so far: 26376.2
If we take 1322 away from 1420, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 10:
If we divide 980 by 661, we get 1 and a remainder of 319.
Write down 1 as next digit of the result. 
Result so far: 26376.21
If we take 661 away from 980, we end up with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Going ahead to step 11:
The number 661 fits into 3190 4 times, leaving a remainder of 546.
Write down 4 as next digit of the result. 
Result so far: 26376.214
If we take 2644 away from 3190, we end up with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Going ahead to step 12:
When dividing 5460 by 661, we get 8 with a remainder of 172.
The next digit of our result is 8. 
Result so far: 26376.2148
The remainder is 172 after subtracting 5288 from 5460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 13:
661 goes into 1720 2 times with a remainder of 398.
The next digit of our result is 2. 
Result so far: 26376.21482
If we subtract 1322 from 1720, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Step 14:
661 goes into 3980 6 times with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 26376.214826
If we take 3966 away from 3980, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 15:
140 divided by 661 is 0 with a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 26376.214826
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 16:
If we divide 1400 by 661, we get 2 and a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 26376.21482602
If we take 1322 away from 1400, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The quotient of the division is 26376.21482602, and the remainder is 7.8e-08.
