42257701 ÷ 661 
Let's see how many times 661 fits into 42257701.

Step 1:
The number 661 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 661

On to step 2:
When dividing 42 by 661, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 661

Let's proceed to step 3:
When dividing 422 by 661, we get 0 with a remainder of 422.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 422, we get 422.
Take the next digit (5) from the dividend and append it to 422, then repeat: 4225 / 661

Step 4:
4225 divided by 661 is 6 with a remainder of 259.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 3966 from 4225 and we're left with 259.
Append the next digit (7) from the dividend to 259 and continue with: 2597 / 661

Step 5:
661 can be fit into 2597 3 times, resulting in a remainder of 614.
Put 3 as the next digit of the answer. 
Result so far: 63.0
If we take 1983 away from 2597, we end up with 614.
Include the next digit (7) from the dividend after 614, then repeat: 6147 / 661

Moving on to step 6:
When dividing 6147 by 661, we get 9 with a remainder of 198.
The next digit of our result is 9. 
Result so far: 639.0
Subtract 5949 from 6147 to get 198.
Grab the next digit (0) from the dividend, add it to 198, then carry on: 1980 / 661

Moving on to step 7:
The number 661 fits into 1980 2 times, leaving a remainder of 658.
The number 2 becomes the next digit in our result. 
Result so far: 6392.0
The remainder is 658 after subtracting 1322 from 1980.
Fetch the next digit (1) from the dividend, attach it to 658 and continue: 6581 / 661

Advancing to step 8:
The number 661 fits into 6581 9 times, leaving a remainder of 632.
Use 9 as the next digit of our solution. 
Result so far: 63929.0
Subtracting 5949 from 6581 leaves us with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Moving on to step 9:
661 goes into 6320 9 times with a remainder of 371.
Put 9 as the next digit of the answer. 
Result so far: 63929.9
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.

Let's proceed to step 10:
If we divide 3710 by 661, we get 5 and a remainder of 405.
Put 5 as the next digit of the answer. 
Result so far: 63929.95
If we subtract 3305 from 3710, we get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 11:
If we divide 4050 by 661, we get 6 and a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 63929.956
Subtracting 3966 from 4050 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 12:
The number 661 fits into 840 1 times, leaving a remainder of 179.
The number 1 becomes the next digit in our result. 
Result so far: 63929.9561
Subtracting 661 from 840 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Moving on to step 13:
661 goes into 1790 2 times with a remainder of 468.
Write down 2 as next digit of the result. 
Result so far: 63929.95612
If we take 1322 away from 1790, we end up with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Moving on to step 14:
661 goes into 4680 7 times with a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 63929.956127
If we subtract 4627 from 4680, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 15:
530 divided by 661 is 0 with a remainder of 530.
The next digit of our result is 0. 
Result so far: 63929.956127
If we take 0 away from 530, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 16:
When dividing 5300 by 661, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 63929.95612708
Subtracting 5288 from 5300 leaves us 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 quotient of the division is 63929.95612708, and the remainder is 1.2e-08.
