We look at the division of 374611 by 21 
We want to figure out the number of times 374611 can be divided by 21.

Going ahead to step 1:
The number 21 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 21

Let's proceed to step 2:
21 can be fit into 37 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 21 away from 37, we end up with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 21

Moving on to step 3:
The number 21 fits into 164 7 times, leaving a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 147 from 164 and we're left with 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 21

Moving on to step 4:
21 can be fit into 176 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
Deduct 168 from 176 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 21

On to step 5:
21 can be fit into 81 3 times, resulting in a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 1783.0
Deduct 63 from 81 and we're left with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 21

Step 6:
21 can be fit into 181 8 times, resulting in a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 17838.0
If we take 168 away from 181, we end up 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.

Moving on to step 7:
The number 21 fits into 130 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 17838.6
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
The number 21 fits into 40 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 17838.61
If we subtract 21 from 40, we get 19.
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 9:
If we divide 190 by 21, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 17838.619
Subtracting 189 from 190 leaves us 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.

Advancing to step 10:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 17838.619
Deduct 0 from 10 and we're left 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.

Let's proceed to step 11:
If we divide 100 by 21, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 17838.61904
Deduct 84 from 100 and we're left 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 12:
The number 21 fits into 160 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 17838.619047
Subtracting 147 from 160 leaves us 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.

Moving on to step 13:
When dividing 130 by 21, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 17838.6190476
If we take 126 away from 130, we end up 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.

Moving on to step 14:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 17838.61904761
If we take 21 away from 40, we end up 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.

After the division, we end up with 17838.61904761 and a remainder of 1.9e-08.
