77846 divided by 21 
We want to figure out the number of times 77846 can be divided by 21.

On to step 1:
7 divided by 21 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 21

On to step 2:
When dividing 77 by 21, we get 3 with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 63 from 77 leaves us with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 21

Going ahead to step 3:
When dividing 148 by 21, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 37.0
Deduct 147 from 148 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 21

Moving on to step 4:
The number 21 fits into 14 0 times, leaving a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 370.0
Deduct 0 from 14 and we're left with 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 21

Let's proceed to step 5:
146 divided by 21 is 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 3706.0
The remainder is 20 after subtracting 126 from 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 6:
21 goes into 200 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 3706.9
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
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: 3706.95
Subtracting 105 from 110 leaves us with 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 8:
When dividing 50 by 21, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 3706.952
Subtract 42 from 50 to get 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 9:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 3706.9523
If we take 63 away from 80, we end up 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.

On to step 10:
21 goes into 170 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 3706.95238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
20 divided by 21 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 3706.95238
Subtract 0 from 20 to 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.

Moving on to step 12:
The number 21 fits into 200 9 times, leaving a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 3706.9523809
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 13:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3706.95238095
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.

The final outcome is 3706.95238095, with a leftover of 5e-09.
