21275977 divided by 837 
Our goal is to divide 21275977 by 837.

Let's proceed to step 1:
If we divide 2 by 837, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 837

Advancing to step 2:
The number 837 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 837

On to step 3:
If we divide 212 by 837, we get 0 and a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 212 to get 212.
Take the next digit (7) from the dividend and append it to 212, then repeat: 2127 / 837

Going ahead to step 4:
837 can be fit into 2127 2 times, resulting in a remainder of 453.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1674 from 2127 leaves us with 453.
Bring next digit (5) of the dividend behind the 453 and repeat the process: 4535 / 837

On to step 5:
837 goes into 4535 5 times with a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 4185 from 4535 to get 350.
Take the next digit (9) from the dividend and append it to 350, then repeat: 3509 / 837

Step 6:
If we divide 3509 by 837, we get 4 and a remainder of 161.
Record the quotient 4 as the next digit in the result. 
Result so far: 254.0
Subtracting 3348 from 3509 leaves us with 161.
Take the next digit (7) from the dividend and append it to 161, then repeat: 1617 / 837

Let's proceed to step 7:
If we divide 1617 by 837, we get 1 and a remainder of 780.
Record the quotient 1 as the next digit in the result. 
Result so far: 2541.0
If we take 837 away from 1617, we end up with 780.
Bring next digit (7) of the dividend behind the 780 and repeat the process: 7807 / 837

Advancing to step 8:
837 can be fit into 7807 9 times, resulting in a remainder of 274.
Write down 9 as next digit of the result. 
Result so far: 25419.0
If we take 7533 away from 7807, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 9:
2740 divided by 837 is 3 with a remainder of 229.
Write down 3 as next digit of the result. 
Result so far: 25419.3
Subtract 2511 from 2740 to get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Going ahead to step 10:
The number 837 fits into 2290 2 times, leaving a remainder of 616.
Use 2 as the next digit of our solution. 
Result so far: 25419.32
If we take 1674 away from 2290, we end up with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Going ahead to step 11:
When dividing 6160 by 837, we get 7 with a remainder of 301.
Write down 7 as next digit of the result. 
Result so far: 25419.327
Deduct 5859 from 6160 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 12:
837 can be fit into 3010 3 times, resulting in a remainder of 499.
The number 3 becomes the next digit in our result. 
Result so far: 25419.3273
Subtracting 2511 from 3010 leaves us with 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Advancing to step 13:
837 can be fit into 4990 5 times, resulting in a remainder of 805.
Record the quotient 5 as the next digit in the result. 
Result so far: 25419.32735
Deduct 4185 from 4990 and we're left with 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Moving on to step 14:
837 can be fit into 8050 9 times, resulting in a remainder of 517.
Write down 9 as next digit of the result. 
Result so far: 25419.327359
If we subtract 7533 from 8050, we get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

On to step 15:
If we divide 5170 by 837, we get 6 and a remainder of 148.
Record the quotient 6 as the next digit in the result. 
Result so far: 25419.3273596
The remainder is 148 after subtracting 5022 from 5170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 16:
837 can be fit into 1480 1 times, resulting in a remainder of 643.
Use 1 as the next digit of our solution. 
Result so far: 25419.32735961
Deduct 837 from 1480 and we're left with 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

After the division, we end up with 25419.32735961 and a remainder of 6.43e-07.
