We divide 934450 by 643
The aim is to understand the frequency of 643 in 934450.

Going ahead to step 1:
643 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 643

On to step 2:
643 goes into 93 0 times with a remainder of 93.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 93 after subtracting 0 from 93.
Append the next digit (4) from the dividend to 93 and continue with: 934 / 643

Going ahead to step 3:
643 can be fit into 934 1 times, resulting in a remainder of 291.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 643 from 934 and we're left with 291.
Bring next digit (4) of the dividend behind the 291 and repeat the process: 2914 / 643

Going ahead to step 4:
2914 divided by 643 is 4 with a remainder of 342.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 2572 from 2914, we get 342.
Include the next digit (5) from the dividend after 342, then repeat: 3425 / 643

Moving on to step 5:
3425 divided by 643 is 5 with a remainder of 210.
Record the quotient 5 as the next digit in the result. 
Result so far: 145.0
Subtract 3215 from 3425 to get 210.
Include the next digit (0) from the dividend after 210, then repeat: 2100 / 643

Let's proceed to step 6:
643 can be fit into 2100 3 times, resulting in a remainder of 171.
The number 3 becomes the next digit in our result. 
Result so far: 1453.0
Subtracting 1929 from 2100 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

On to step 7:
If we divide 1710 by 643, we get 2 and a remainder of 424.
Record the quotient 2 as the next digit in the result. 
Result so far: 1453.2
If we subtract 1286 from 1710, we get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Step 8:
The number 643 fits into 4240 6 times, leaving a remainder of 382.
Record the quotient 6 as the next digit in the result. 
Result so far: 1453.26
The remainder is 382 after subtracting 3858 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 9:
643 can be fit into 3820 5 times, resulting in a remainder of 605.
Record the quotient 5 as the next digit in the result. 
Result so far: 1453.265
The remainder is 605 after subtracting 3215 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

On to step 10:
6050 divided by 643 is 9 with a remainder of 263.
The number 9 becomes the next digit in our result. 
Result so far: 1453.2659
Subtracting 5787 from 6050 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Step 11:
The number 643 fits into 2630 4 times, leaving a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 1453.26594
Subtract 2572 from 2630 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 12:
The number 643 fits into 580 0 times, leaving a remainder of 580.
Write down 0 as next digit of the result. 
Result so far: 1453.26594
If we take 0 away from 580, we end up 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.

Advancing to step 13:
643 can be fit into 5800 9 times, resulting in a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 1453.2659409
The remainder is 13 after subtracting 5787 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 14:
643 can be fit into 130 0 times, resulting in a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 1453.2659409
If we take 0 away from 130, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The quotient of the division is 1453.2659409, and the remainder is 1.3e-07.
