68175511 ÷ 661 
We want to figure out the number of times 68175511 can be divided by 661.

Moving on to step 1:
661 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 661

Let's proceed to step 2:
If we divide 68 by 661, we get 0 and a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Include the next digit (1) from the dividend after 68, then repeat: 681 / 661

On to step 3:
661 can be fit into 681 1 times, resulting in a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 661 away from 681, we end up with 20.
Include the next digit (7) from the dividend after 20, then repeat: 207 / 661

Advancing to step 4:
If we divide 207 by 661, we get 0 and a remainder of 207.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 207 to get 207.
Include the next digit (5) from the dividend after 207, then repeat: 2075 / 661

Step 5:
661 can be fit into 2075 3 times, resulting in a remainder of 92.
Use 3 as the next digit of our solution. 
Result so far: 103.0
If we take 1983 away from 2075, we end up with 92.
Append the next digit (5) from the dividend to 92 and continue with: 925 / 661

Advancing to step 6:
The number 661 fits into 925 1 times, leaving a remainder of 264.
The next digit of our result is 1. 
Result so far: 1031.0
If we take 661 away from 925, we end up with 264.
Take the next digit (1) from the dividend and append it to 264, then repeat: 2641 / 661

Let's proceed to step 7:
When dividing 2641 by 661, we get 3 with a remainder of 658.
Put 3 as the next digit of the answer. 
Result so far: 10313.0
If we subtract 1983 from 2641, we get 658.
Take the next digit (1) from the dividend and append it to 658, then repeat: 6581 / 661

Advancing to step 8:
6581 divided by 661 is 9 with a remainder of 632.
Record the quotient 9 as the next digit in the result. 
Result so far: 103139.0
The remainder is 632 after subtracting 5949 from 6581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Step 9:
661 can be fit into 6320 9 times, resulting in a remainder of 371.
Put 9 as the next digit of the answer. 
Result so far: 103139.9
Subtract 5949 from 6320 to get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Going ahead to step 10:
661 goes into 3710 5 times with a remainder of 405.
Record the quotient 5 as the next digit in the result. 
Result so far: 103139.95
The remainder is 405 after subtracting 3305 from 3710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 11:
When dividing 4050 by 661, we get 6 with a remainder of 84.
The next digit of our result is 6. 
Result so far: 103139.956
If we subtract 3966 from 4050, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 12:
The number 661 fits into 840 1 times, leaving a remainder of 179.
Use 1 as the next digit of our solution. 
Result so far: 103139.9561
The remainder is 179 after subtracting 661 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Step 13:
If we divide 1790 by 661, we get 2 and a remainder of 468.
Record the quotient 2 as the next digit in the result. 
Result so far: 103139.95612
The remainder is 468 after subtracting 1322 from 1790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Going ahead to step 14:
The number 661 fits into 4680 7 times, leaving a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 103139.956127
The remainder is 53 after subtracting 4627 from 4680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 15:
661 goes into 530 0 times with a remainder of 530.
The number 0 becomes the next digit in our result. 
Result so far: 103139.956127
Subtract 0 from 530 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 16:
5300 divided by 661 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 103139.95612708
If we take 5288 away from 5300, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 103139.95612708, with a leftover of 1.2e-08.
