We divide 21123738 by 931
We want to figure out the number of times 21123738 can be divided by 931.

Let's proceed to step 1:
The number 931 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
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 / 931

Let's proceed to step 2:
When dividing 21 by 931, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 931

Let's proceed to step 3:
If we divide 211 by 931, we get 0 and a remainder of 211.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 211 after subtracting 0 from 211.
Take the next digit (2) from the dividend and append it to 211, then repeat: 2112 / 931

Let's proceed to step 4:
2112 divided by 931 is 2 with a remainder of 250.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1862 from 2112, we get 250.
Include the next digit (3) from the dividend after 250, then repeat: 2503 / 931

Let's proceed to step 5:
The number 931 fits into 2503 2 times, leaving a remainder of 641.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 641 after subtracting 1862 from 2503.
Append the next digit (7) from the dividend to 641 and continue with: 6417 / 931

Step 6:
931 can be fit into 6417 6 times, resulting in a remainder of 831.
Record the quotient 6 as the next digit in the result. 
Result so far: 226.0
The remainder is 831 after subtracting 5586 from 6417.
Grab the next digit (3) from the dividend, add it to 831, then carry on: 8313 / 931

On to step 7:
931 goes into 8313 8 times with a remainder of 865.
The next digit of our result is 8. 
Result so far: 2268.0
If we take 7448 away from 8313, we end up with 865.
Grab the next digit (8) from the dividend, add it to 865, then carry on: 8658 / 931

On to step 8:
8658 divided by 931 is 9 with a remainder of 279.
The number 9 becomes the next digit in our result. 
Result so far: 22689.0
Subtracting 8379 from 8658 leaves us with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Advancing to step 9:
When dividing 2790 by 931, we get 2 with a remainder of 928.
The number 2 becomes the next digit in our result. 
Result so far: 22689.2
Subtract 1862 from 2790 to get 928.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9280, and continue the process.

On to step 10:
9280 divided by 931 is 9 with a remainder of 901.
Write down 9 as next digit of the result. 
Result so far: 22689.29
Subtract 8379 from 9280 to get 901.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9010, and continue the process.

Let's proceed to step 11:
9010 divided by 931 is 9 with a remainder of 631.
Put 9 as the next digit of the answer. 
Result so far: 22689.299
The remainder is 631 after subtracting 8379 from 9010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

The final outcome is 22689.299, with a leftover of 0.0631.
