We divide 1559746 by 629
The aim is to understand the frequency of 629 in 1559746.

Step 1:
When dividing 1 by 629, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 629

Moving on to step 2:
The number 629 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 629

On to step 3:
When dividing 155 by 629, we get 0 with a remainder of 155.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 155, we get 155.
Take the next digit (9) from the dividend and append it to 155, then repeat: 1559 / 629

On to step 4:
The number 629 fits into 1559 2 times, leaving a remainder of 301.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 301 after subtracting 1258 from 1559.
Grab the next digit (7) from the dividend, add it to 301, then carry on: 3017 / 629

Moving on to step 5:
629 goes into 3017 4 times with a remainder of 501.
The next digit of our result is 4. 
Result so far: 24.0
Deduct 2516 from 3017 and we're left with 501.
Bring next digit (4) of the dividend behind the 501 and repeat the process: 5014 / 629

Let's proceed to step 6:
If we divide 5014 by 629, we get 7 and a remainder of 611.
Use 7 as the next digit of our solution. 
Result so far: 247.0
If we subtract 4403 from 5014, we get 611.
Append the next digit (6) from the dividend to 611 and continue with: 6116 / 629

Advancing to step 7:
629 can be fit into 6116 9 times, resulting in a remainder of 455.
The number 9 becomes the next digit in our result. 
Result so far: 2479.0
If we subtract 5661 from 6116, we get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Going ahead to step 8:
629 can be fit into 4550 7 times, resulting in a remainder of 147.
The number 7 becomes the next digit in our result. 
Result so far: 2479.7
If we subtract 4403 from 4550, we get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Moving on to step 9:
629 goes into 1470 2 times with a remainder of 212.
The number 2 becomes the next digit in our result. 
Result so far: 2479.72
Deduct 1258 from 1470 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 10:
If we divide 2120 by 629, we get 3 and a remainder of 233.
Use 3 as the next digit of our solution. 
Result so far: 2479.723
Subtract 1887 from 2120 to get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Step 11:
When dividing 2330 by 629, we get 3 with a remainder of 443.
Record the quotient 3 as the next digit in the result. 
Result so far: 2479.7233
If we subtract 1887 from 2330, we get 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

The final result is 2479.7233 with a remainder of 0.00443.
