We divide 21101604 by 770
We're looking to find how many times 770 goes into 21101604.

Advancing to step 1:
2 divided by 770 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 770

Moving on to step 2:
The number 770 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 770

Step 3:
770 can be fit into 211 0 times, resulting in a remainder of 211.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 211 to get 211.
Bring next digit (0) of the dividend behind the 211 and repeat the process: 2110 / 770

Going ahead to step 4:
2110 divided by 770 is 2 with a remainder of 570.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 1540 from 2110 leaves us with 570.
Fetch the next digit (1) from the dividend, attach it to 570 and continue: 5701 / 770

Let's proceed to step 5:
The number 770 fits into 5701 7 times, leaving a remainder of 311.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we take 5390 away from 5701, we end up with 311.
Include the next digit (6) from the dividend after 311, then repeat: 3116 / 770

Going ahead to step 6:
770 goes into 3116 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 274.0
Deduct 3080 from 3116 and we're left with 36.
Bring next digit (0) of the dividend behind the 36 and repeat the process: 360 / 770

Moving on to step 7:
360 divided by 770 is 0 with a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 2740.0
The remainder is 360 after subtracting 0 from 360.
Take the next digit (4) from the dividend and append it to 360, then repeat: 3604 / 770

On to step 8:
770 goes into 3604 4 times with a remainder of 524.
Write down 4 as next digit of the result. 
Result so far: 27404.0
Subtracting 3080 from 3604 leaves us with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Moving on to step 9:
5240 divided by 770 is 6 with a remainder of 620.
The number 6 becomes the next digit in our result. 
Result so far: 27404.6
Subtract 4620 from 5240 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 10:
When dividing 6200 by 770, we get 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 27404.68
The remainder is 40 after subtracting 6160 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
400 divided by 770 is 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 27404.68
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 12:
770 can be fit into 4000 5 times, resulting in a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 27404.6805
If we subtract 3850 from 4000, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 13:
The number 770 fits into 1500 1 times, leaving a remainder of 730.
Record the quotient 1 as the next digit in the result. 
Result so far: 27404.68051
Subtract 770 from 1500 to get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Step 14:
770 goes into 7300 9 times with a remainder of 370.
Use 9 as the next digit of our solution. 
Result so far: 27404.680519
Subtracting 6930 from 7300 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 15:
The number 770 fits into 3700 4 times, leaving a remainder of 620.
Put 4 as the next digit of the answer. 
Result so far: 27404.6805194
Subtract 3080 from 3700 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 16:
When dividing 6200 by 770, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 27404.68051948
The remainder is 40 after subtracting 6160 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 27404.68051948 with a balance of 4e-08.
