Let's divide 210974 by 84
We want to figure out the number of times 210974 can be divided by 84.

Moving on to step 1:
2 divided by 84 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 84

Moving on to step 2:
When dividing 21 by 84, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 84

Advancing to step 3:
If we divide 210 by 84, we get 2 and a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 168 from 210, we get 42.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 84

Advancing to step 4:
The number 84 fits into 429 5 times, leaving a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Deduct 420 from 429 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 84

Advancing to step 5:
84 can be fit into 97 1 times, resulting in a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 251.0
If we take 84 away from 97, we end up with 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 84

Moving on to step 6:
If we divide 134 by 84, we get 1 and a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 2511.0
Subtracting 84 from 134 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
The number 84 fits into 500 5 times, leaving a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 2511.5
The remainder is 80 after subtracting 420 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 8:
If we divide 800 by 84, we get 9 and a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 2511.59
Subtract 756 from 800 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
When dividing 440 by 84, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 2511.595
Subtracting 420 from 440 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
84 goes into 200 2 times with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 2511.5952
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
If we divide 320 by 84, we get 3 and a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 2511.59523
If we subtract 252 from 320, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
84 can be fit into 680 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 2511.595238
Subtracting 672 from 680 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.

Moving on to step 13:
The number 84 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 2511.595238
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 14:
If we divide 800 by 84, we get 9 and a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 2511.59523809
If we take 756 away from 800, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 2511.59523809, with a leftover of 4.4e-08.
