We divide 616601 by 21
We're looking to find how many times 21 goes into 616601.

Advancing to step 1:
If we divide 6 by 21, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 21

Step 2:
If we divide 61 by 21, we get 2 and a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 42 from 61 to get 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 21

Step 3:
21 goes into 196 9 times with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Subtracting 189 from 196 leaves us with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 21

Going ahead to step 4:
When dividing 76 by 21, we get 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 293.0
If we subtract 63 from 76, we get 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 21

Advancing to step 5:
If we divide 130 by 21, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 2936.0
Subtracting 126 from 130 leaves us with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 21

Step 6:
When dividing 41 by 21, we get 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 29361.0
If we subtract 21 from 41, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 29361.9
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
When dividing 110 by 21, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 29361.95
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
50 divided by 21 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 29361.952
Subtracting 42 from 50 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
21 goes into 80 3 times with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 29361.9523
Subtracting 63 from 80 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 11:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 29361.95238
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
21 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 29361.95238
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
200 divided by 21 is 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 29361.9523809
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 14:
21 goes into 110 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 29361.95238095
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 29361.95238095 with a remainder of 5e-09.
