We look at the division of 55787175 by 661 
We want to figure out the number of times 55787175 can be divided by 661.

Going ahead to step 1:
If we divide 5 by 661, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 661

Moving on to step 2:
If we divide 55 by 661, we get 0 and a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Fetch the next digit (7) from the dividend, attach it to 55 and continue: 557 / 661

Moving on to step 3:
If we divide 557 by 661, we get 0 and a remainder of 557.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 557 to get 557.
Grab the next digit (8) from the dividend, add it to 557, then carry on: 5578 / 661

Step 4:
When dividing 5578 by 661, we get 8 with a remainder of 290.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 5288 from 5578, we get 290.
Include the next digit (7) from the dividend after 290, then repeat: 2907 / 661

Going ahead to step 5:
When dividing 2907 by 661, we get 4 with a remainder of 263.
Use 4 as the next digit of our solution. 
Result so far: 84.0
The remainder is 263 after subtracting 2644 from 2907.
Append the next digit (1) from the dividend to 263 and continue with: 2631 / 661

Going ahead to step 6:
If we divide 2631 by 661, we get 3 and a remainder of 648.
Write down 3 as next digit of the result. 
Result so far: 843.0
Subtracting 1983 from 2631 leaves us with 648.
Fetch the next digit (7) from the dividend, attach it to 648 and continue: 6487 / 661

Moving on to step 7:
When dividing 6487 by 661, we get 9 with a remainder of 538.
Use 9 as the next digit of our solution. 
Result so far: 8439.0
If we take 5949 away from 6487, we end up with 538.
Bring next digit (5) of the dividend behind the 538 and repeat the process: 5385 / 661

Going ahead to step 8:
The number 661 fits into 5385 8 times, leaving a remainder of 97.
Write down 8 as next digit of the result. 
Result so far: 84398.0
The remainder is 97 after subtracting 5288 from 5385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 9:
The number 661 fits into 970 1 times, leaving a remainder of 309.
Put 1 as the next digit of the answer. 
Result so far: 84398.1
If we take 661 away from 970, we end up with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

On to step 10:
3090 divided by 661 is 4 with a remainder of 446.
The number 4 becomes the next digit in our result. 
Result so far: 84398.14
Subtracting 2644 from 3090 leaves us with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

On to step 11:
4460 divided by 661 is 6 with a remainder of 494.
The number 6 becomes the next digit in our result. 
Result so far: 84398.146
Subtracting 3966 from 4460 leaves us with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Moving on to step 12:
The number 661 fits into 4940 7 times, leaving a remainder of 313.
Record the quotient 7 as the next digit in the result. 
Result so far: 84398.1467
If we take 4627 away from 4940, we end up with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Going ahead to step 13:
When dividing 3130 by 661, we get 4 with a remainder of 486.
The number 4 becomes the next digit in our result. 
Result so far: 84398.14674
Subtract 2644 from 3130 to get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Advancing to step 14:
If we divide 4860 by 661, we get 7 and a remainder of 233.
Use 7 as the next digit of our solution. 
Result so far: 84398.146747
Subtract 4627 from 4860 to get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Advancing to step 15:
661 can be fit into 2330 3 times, resulting in a remainder of 347.
The next digit of our result is 3. 
Result so far: 84398.1467473
If we subtract 1983 from 2330, we get 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Moving on to step 16:
If we divide 3470 by 661, we get 5 and a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 84398.14674735
The remainder is 165 after subtracting 3305 from 3470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

After the division, we end up with 84398.14674735 and a remainder of 1.65e-07.
