We look at the division of 63571721 by 939 
We're looking to find how many times 939 goes into 63571721.

Step 1:
If we divide 6 by 939, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 939

Advancing to step 2:
63 divided by 939 is 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Bring next digit (5) of the dividend behind the 63 and repeat the process: 635 / 939

Step 3:
The number 939 fits into 635 0 times, leaving a remainder of 635.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 635 and we're left with 635.
Fetch the next digit (7) from the dividend, attach it to 635 and continue: 6357 / 939

Going ahead to step 4:
6357 divided by 939 is 6 with a remainder of 723.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 5634 from 6357 leaves us with 723.
Append the next digit (1) from the dividend to 723 and continue with: 7231 / 939

Moving on to step 5:
7231 divided by 939 is 7 with a remainder of 658.
Use 7 as the next digit of our solution. 
Result so far: 67.0
If we subtract 6573 from 7231, we get 658.
Take the next digit (7) from the dividend and append it to 658, then repeat: 6587 / 939

Going ahead to step 6:
The number 939 fits into 6587 7 times, leaving a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 677.0
Deduct 6573 from 6587 and we're left with 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 939

Moving on to step 7:
The number 939 fits into 142 0 times, leaving a remainder of 142.
Put 0 as the next digit of the answer. 
Result so far: 6770.0
The remainder is 142 after subtracting 0 from 142.
Take the next digit (1) from the dividend and append it to 142, then repeat: 1421 / 939

Let's proceed to step 8:
When dividing 1421 by 939, we get 1 with a remainder of 482.
Put 1 as the next digit of the answer. 
Result so far: 67701.0
Subtracting 939 from 1421 leaves us with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Moving on to step 9:
The number 939 fits into 4820 5 times, leaving a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 67701.5
The remainder is 125 after subtracting 4695 from 4820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 10:
The number 939 fits into 1250 1 times, leaving a remainder of 311.
Write down 1 as next digit of the result. 
Result so far: 67701.51
If we take 939 away from 1250, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Going ahead to step 11:
939 can be fit into 3110 3 times, resulting in a remainder of 293.
Put 3 as the next digit of the answer. 
Result so far: 67701.513
Subtracting 2817 from 3110 leaves us with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Moving on to step 12:
When dividing 2930 by 939, we get 3 with a remainder of 113.
The next digit of our result is 3. 
Result so far: 67701.5133
If we subtract 2817 from 2930, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

In conclusion, the division gives 67701.5133 with a balance of 0.00113.
