601120 divided by 21 
We want to figure out the number of times 601120 can be divided by 21.

Moving on to step 1:
21 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 21

Advancing to step 2:
The number 21 fits into 60 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 42 away from 60, we end up with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 21

Step 3:
21 can be fit into 181 8 times, resulting in a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Deduct 168 from 181 and we're left with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 21

Advancing to step 4:
21 can be fit into 131 6 times, resulting in a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 286.0
Subtracting 126 from 131 leaves us with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 21

Let's proceed to step 5:
When dividing 52 by 21, we get 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 2862.0
Deduct 42 from 52 and we're left with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 21

Going ahead to step 6:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 28624.0
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.

Step 7:
160 divided by 21 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 28624.7
Deduct 147 from 160 and we're left with 13.
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 8:
21 can be fit into 130 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 28624.76
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 9:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 28624.761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 10:
190 divided by 21 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 28624.7619
Subtract 189 from 190 to get 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 11:
When dividing 10 by 21, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 28624.7619
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.

Moving on to step 12:
100 divided by 21 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 28624.761904
If we take 84 away from 100, we end up with 16.
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 13:
21 goes into 160 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 28624.7619047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 14:
21 can be fit into 130 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 28624.76190476
Deduct 126 from 130 and we're left 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.

After the division, we end up with 28624.76190476 and a remainder of 4e-09.
