We divide 70342656 by 21
We're looking to find how many times 21 goes into 70342656.

Let's proceed to step 1:
The number 21 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 21

Step 2:
21 can be fit into 70 3 times, resulting in a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 7 after subtracting 63 from 70.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 21

Going ahead to step 3:
21 can be fit into 73 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we take 63 away from 73, we end up with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 21

Let's proceed to step 4:
104 divided by 21 is 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 334.0
The remainder is 20 after subtracting 84 from 104.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 21

Going ahead to step 5:
When dividing 202 by 21, we get 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 3349.0
If we take 189 away from 202, we end up with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 21

Step 6:
136 divided by 21 is 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 33496.0
Deduct 126 from 136 and we're left with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 21

Step 7:
21 goes into 105 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 334965.0
Subtract 105 from 105 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 21

Advancing to step 8:
6 divided by 21 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 3349650.0
The remainder is 6 after subtracting 0 from 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
If we divide 60 by 21, we get 2 and a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 3349650.2
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
If we divide 180 by 21, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 3349650.28
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
If we divide 120 by 21, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 3349650.285
If we take 105 away from 120, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 3349650.2857
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 13:
The number 21 fits into 30 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 3349650.28571
Subtract 21 from 30 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
90 divided by 21 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 3349650.285714
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 15:
If we divide 60 by 21, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 3349650.2857142
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 16:
21 goes into 180 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 3349650.28571428
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 3349650.28571428 and a remainder of 1.2e-08.
