Let's divide 785446 by 21
We're looking to find how many times 21 goes into 785446.

Advancing to step 1:
When dividing 7 by 21, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 21

Let's proceed to step 2:
21 goes into 78 3 times with a remainder of 15.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 15 after subtracting 63 from 78.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 21

Let's proceed to step 3:
When dividing 155 by 21, we get 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtracting 147 from 155 leaves us with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 21

Going ahead to step 4:
21 can be fit into 84 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 374.0
Deduct 84 from 84 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 21

Going ahead to step 5:
21 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 3740.0
If we take 0 away from 4, we end up with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 21

Let's proceed to step 6:
When dividing 46 by 21, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 37402.0
Subtract 42 from 46 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
21 goes into 40 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 37402.1
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.

Going ahead to step 8:
190 divided by 21 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 37402.19
If we subtract 189 from 190, we 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.

Going ahead to step 9:
21 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 37402.19
Subtracting 0 from 10 leaves us 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 10:
21 goes into 100 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 37402.1904
Subtracting 84 from 100 leaves us 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.

On to step 11:
160 divided by 21 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 37402.19047
If we take 147 away from 160, 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.

Advancing to step 12:
130 divided by 21 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 37402.190476
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
21 goes into 40 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 37402.1904761
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.

Moving on to step 14:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 37402.19047619
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.

Our division results in 37402.19047619 with a remaining 1e-09.
