We divide 13925212 by 645
We want to divide 13925212 by 645.

Let's proceed to step 1:
The number 645 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 645

Going ahead to step 2:
If we divide 13 by 645, we get 0 and a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 645

Let's proceed to step 3:
When dividing 139 by 645, we get 0 with a remainder of 139.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 139, we get 139.
Fetch the next digit (2) from the dividend, attach it to 139 and continue: 1392 / 645

Advancing to step 4:
The number 645 fits into 1392 2 times, leaving a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 1290 from 1392 leaves us with 102.
Take the next digit (5) from the dividend and append it to 102, then repeat: 1025 / 645

Step 5:
1025 divided by 645 is 1 with a remainder of 380.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 645 from 1025 leaves us with 380.
Append the next digit (2) from the dividend to 380 and continue with: 3802 / 645

Step 6:
If we divide 3802 by 645, we get 5 and a remainder of 577.
Record the quotient 5 as the next digit in the result. 
Result so far: 215.0
If we subtract 3225 from 3802, we get 577.
Include the next digit (1) from the dividend after 577, then repeat: 5771 / 645

Advancing to step 7:
645 goes into 5771 8 times with a remainder of 611.
Use 8 as the next digit of our solution. 
Result so far: 2158.0
Subtract 5160 from 5771 to get 611.
Fetch the next digit (2) from the dividend, attach it to 611 and continue: 6112 / 645

Advancing to step 8:
645 goes into 6112 9 times with a remainder of 307.
The next digit of our result is 9. 
Result so far: 21589.0
Subtract 5805 from 6112 to get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Going ahead to step 9:
If we divide 3070 by 645, we get 4 and a remainder of 490.
The next digit of our result is 4. 
Result so far: 21589.4
The remainder is 490 after subtracting 2580 from 3070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 10:
4900 divided by 645 is 7 with a remainder of 385.
Use 7 as the next digit of our solution. 
Result so far: 21589.47
Deduct 4515 from 4900 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 11:
The number 645 fits into 3850 5 times, leaving a remainder of 625.
Write down 5 as next digit of the result. 
Result so far: 21589.475
Subtract 3225 from 3850 to get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Moving on to step 12:
The number 645 fits into 6250 9 times, leaving a remainder of 445.
Write down 9 as next digit of the result. 
Result so far: 21589.4759
Subtracting 5805 from 6250 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Step 13:
645 can be fit into 4450 6 times, resulting in a remainder of 580.
Record the quotient 6 as the next digit in the result. 
Result so far: 21589.47596
Deduct 3870 from 4450 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 14:
The number 645 fits into 5800 8 times, leaving a remainder of 640.
The number 8 becomes the next digit in our result. 
Result so far: 21589.475968
Deduct 5160 from 5800 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 15:
When dividing 6400 by 645, we get 9 with a remainder of 595.
Put 9 as the next digit of the answer. 
Result so far: 21589.4759689
Deduct 5805 from 6400 and we're left with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Going ahead to step 16:
5950 divided by 645 is 9 with a remainder of 145.
Write down 9 as next digit of the result. 
Result so far: 21589.47596899
Deduct 5805 from 5950 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Our division results in 21589.47596899 with a remaining 1.45e-07.
