Let's divide 16969675 by 21
We want to figure out the number of times 16969675 can be divided by 21.

Advancing to step 1:
The number 21 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 21

Advancing to step 2:
If we divide 16 by 21, we get 0 and a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 21

On to step 3:
169 divided by 21 is 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 168 from 169 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 21

Going ahead to step 4:
21 can be fit into 16 0 times, resulting in a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
The remainder is 16 after subtracting 0 from 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 21

Advancing to step 5:
The number 21 fits into 169 8 times, leaving a remainder of 1.
The next digit of our result is 8. 
Result so far: 808.0
Deduct 168 from 169 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 21

Going ahead to step 6:
16 divided by 21 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 8080.0
If we subtract 0 from 16, we get 16.
Grab the next digit (7) from the dividend, add it to 16, then carry on: 167 / 21

Advancing to step 7:
When dividing 167 by 21, we get 7 with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 80807.0
If we take 147 away from 167, we end up with 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 21

Let's proceed to step 8:
If we divide 205 by 21, we get 9 and a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 808079.0
Subtract 189 from 205 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
When dividing 160 by 21, we get 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 808079.7
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
130 divided by 21 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 808079.76
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 11:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 808079.761
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.

Step 12:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 808079.7619
If we take 189 away from 190, we end up 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.

Step 13:
If we divide 10 by 21, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 808079.7619
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 808079.761904
The remainder is 16 after subtracting 84 from 100.
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 15:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 808079.7619047
Deduct 147 from 160 and we're left 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.

Going ahead to step 16:
21 goes into 130 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 808079.76190476
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.

Our division results in 808079.76190476 with a remaining 4e-09.
