We look at the division of 59777866 by 21 
We want to divide 59777866 by 21.

On to step 1:
21 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 21

Let's proceed to step 2:
21 goes into 59 2 times with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 42 from 59 leaves us with 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 21

Step 3:
21 can be fit into 177 8 times, resulting in a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 28.0
The remainder is 9 after subtracting 168 from 177.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 21

Step 4:
21 goes into 97 4 times with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 284.0
Subtract 84 from 97 to get 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 21

Going ahead to step 5:
The number 21 fits into 137 6 times, leaving a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 2846.0
If we take 126 away from 137, we end up with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 21

Let's proceed to step 6:
If we divide 118 by 21, we get 5 and a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 28465.0
If we take 105 away from 118, we end up with 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 21

Moving on to step 7:
21 goes into 136 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 284656.0
If we subtract 126 from 136, we get 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 21

Going ahead to step 8:
When dividing 106 by 21, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 2846565.0
Deduct 105 from 106 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
10 divided by 21 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 2846565.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
100 divided by 21 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 2846565.04
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 2846565.047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 12:
130 divided by 21 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 2846565.0476
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
40 divided by 21 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 2846565.04761
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 14:
21 goes into 190 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 2846565.047619
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 15:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 2846565.047619
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 16:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 2846565.04761904
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 2846565.04761904 with a balance of 1.6e-08.
