We divide 18710364 by 21
Our goal is to divide 18710364 by 21.

Moving on to step 1:
1 divided by 21 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 21

On to step 2:
21 goes into 18 0 times with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 21

Let's proceed to step 3:
If we divide 187 by 21, we get 8 and a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 168 from 187 and we're left with 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 21

Let's proceed to step 4:
When dividing 191 by 21, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Subtract 189 from 191 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 21

On to step 5:
If we divide 20 by 21, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 890.0
Deduct 0 from 20 and we're left with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 21

On to step 6:
When dividing 203 by 21, we get 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 8909.0
If we take 189 away from 203, we end up with 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 21

Going ahead to step 7:
When dividing 146 by 21, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 89096.0
The remainder is 20 after subtracting 126 from 146.
Grab the next digit (4) from the dividend, add it to 20, then carry on: 204 / 21

Let's proceed to step 8:
If we divide 204 by 21, we get 9 and a remainder of 15.
The next digit of our result is 9. 
Result so far: 890969.0
If we subtract 189 from 204, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
21 goes into 150 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 890969.7
If we take 147 away from 150, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
When dividing 30 by 21, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 890969.71
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.

Advancing to step 11:
21 goes into 90 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 890969.714
Subtracting 84 from 90 leaves us 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.

Advancing to step 12:
21 goes into 60 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 890969.7142
Deduct 42 from 60 and we're left 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.

On to step 13:
If we divide 180 by 21, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 890969.71428
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.

Going ahead to step 14:
The number 21 fits into 120 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 890969.714285
Deduct 105 from 120 and we're left 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.

Advancing to step 15:
21 goes into 150 7 times with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 890969.7142857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 16:
The number 21 fits into 30 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 890969.71428571
If we take 21 away from 30, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 890969.71428571 with a remaining 9e-09.
