51701721 divided by 707 
Our goal is to divide 51701721 by 707.

Moving on to step 1:
707 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 707

Moving on to step 2:
707 can be fit into 51 0 times, resulting in a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 707

Step 3:
517 divided by 707 is 0 with a remainder of 517.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 517 leaves us with 517.
Take the next digit (0) from the dividend and append it to 517, then repeat: 5170 / 707

On to step 4:
When dividing 5170 by 707, we get 7 with a remainder of 221.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 4949 from 5170 and we're left with 221.
Fetch the next digit (1) from the dividend, attach it to 221 and continue: 2211 / 707

Let's proceed to step 5:
If we divide 2211 by 707, we get 3 and a remainder of 90.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Deduct 2121 from 2211 and we're left with 90.
Fetch the next digit (7) from the dividend, attach it to 90 and continue: 907 / 707

On to step 6:
707 can be fit into 907 1 times, resulting in a remainder of 200.
The next digit of our result is 1. 
Result so far: 731.0
Deduct 707 from 907 and we're left with 200.
Include the next digit (2) from the dividend after 200, then repeat: 2002 / 707

On to step 7:
707 goes into 2002 2 times with a remainder of 588.
The next digit of our result is 2. 
Result so far: 7312.0
If we take 1414 away from 2002, we end up with 588.
Append the next digit (1) from the dividend to 588 and continue with: 5881 / 707

On to step 8:
When dividing 5881 by 707, we get 8 with a remainder of 225.
Record the quotient 8 as the next digit in the result. 
Result so far: 73128.0
Subtract 5656 from 5881 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 9:
707 goes into 2250 3 times with a remainder of 129.
Write down 3 as next digit of the result. 
Result so far: 73128.3
The remainder is 129 after subtracting 2121 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 10:
When dividing 1290 by 707, we get 1 with a remainder of 583.
Put 1 as the next digit of the answer. 
Result so far: 73128.31
Subtract 707 from 1290 to get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Advancing to step 11:
5830 divided by 707 is 8 with a remainder of 174.
The next digit of our result is 8. 
Result so far: 73128.318
The remainder is 174 after subtracting 5656 from 5830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 12:
707 can be fit into 1740 2 times, resulting in a remainder of 326.
The next digit of our result is 2. 
Result so far: 73128.3182
The remainder is 326 after subtracting 1414 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 13:
707 can be fit into 3260 4 times, resulting in a remainder of 432.
The next digit of our result is 4. 
Result so far: 73128.31824
The remainder is 432 after subtracting 2828 from 3260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 14:
If we divide 4320 by 707, we get 6 and a remainder of 78.
Put 6 as the next digit of the answer. 
Result so far: 73128.318246
If we subtract 4242 from 4320, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 15:
780 divided by 707 is 1 with a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 73128.3182461
If we take 707 away from 780, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 16:
707 can be fit into 730 1 times, resulting in a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 73128.31824611
If we subtract 707 from 730, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 73128.31824611, with a leftover of 2.3e-08.
