601161 ÷ 21 
We're looking to find how many times 21 goes into 601161.

Let's proceed to step 1:
The number 21 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 21

Going ahead to step 2:
The number 21 fits into 60 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 18 after subtracting 42 from 60.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 21

Step 3:
21 can be fit into 181 8 times, resulting in a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 168 from 181 leaves us with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 21

Going ahead to step 4:
If we divide 131 by 21, we get 6 and a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 286.0
If we take 126 away from 131, we end up with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 21

Going ahead to step 5:
56 divided by 21 is 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 2862.0
Subtract 42 from 56 to get 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 21

Step 6:
21 goes into 141 6 times with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 28626.0
Deduct 126 from 141 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 28626.7
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
If we divide 30 by 21, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 28626.71
If we take 21 away from 30, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
21 can be fit into 90 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 28626.714
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
If we divide 60 by 21, we get 2 and a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 28626.7142
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 11:
21 can be fit into 180 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 28626.71428
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
21 can be fit into 120 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 28626.714285
Deduct 105 from 120 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 28626.7142857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 14:
When dividing 30 by 21, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 28626.71428571
The remainder is 9 after subtracting 21 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

After the division, we end up with 28626.71428571 and a remainder of 9e-09.
