1391454 divided by 629 
The aim is to understand the frequency of 629 in 1391454.

Let's proceed to step 1:
When dividing 1 by 629, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 629

Moving on to step 2:
If we divide 13 by 629, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 629

On to step 3:
The number 629 fits into 139 0 times, leaving a remainder of 139.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 139 to get 139.
Fetch the next digit (1) from the dividend, attach it to 139 and continue: 1391 / 629

On to step 4:
629 goes into 1391 2 times with a remainder of 133.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1258 from 1391 and we're left with 133.
Grab the next digit (4) from the dividend, add it to 133, then carry on: 1334 / 629

Going ahead to step 5:
When dividing 1334 by 629, we get 2 with a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
The remainder is 76 after subtracting 1258 from 1334.
Fetch the next digit (5) from the dividend, attach it to 76 and continue: 765 / 629

On to step 6:
765 divided by 629 is 1 with a remainder of 136.
The next digit of our result is 1. 
Result so far: 221.0
If we take 629 away from 765, we end up with 136.
Append the next digit (4) from the dividend to 136 and continue with: 1364 / 629

Going ahead to step 7:
If we divide 1364 by 629, we get 2 and a remainder of 106.
Put 2 as the next digit of the answer. 
Result so far: 2212.0
Subtracting 1258 from 1364 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 8:
1060 divided by 629 is 1 with a remainder of 431.
Write down 1 as next digit of the result. 
Result so far: 2212.1
If we subtract 629 from 1060, we get 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Moving on to step 9:
629 can be fit into 4310 6 times, resulting in a remainder of 536.
Record the quotient 6 as the next digit in the result. 
Result so far: 2212.16
Deduct 3774 from 4310 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 10:
629 goes into 5360 8 times with a remainder of 328.
The next digit of our result is 8. 
Result so far: 2212.168
Deduct 5032 from 5360 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 11:
The number 629 fits into 3280 5 times, leaving a remainder of 135.
Use 5 as the next digit of our solution. 
Result so far: 2212.1685
Deduct 3145 from 3280 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 12:
The number 629 fits into 1350 2 times, leaving a remainder of 92.
The number 2 becomes the next digit in our result. 
Result so far: 2212.16852
Subtract 1258 from 1350 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 13:
When dividing 920 by 629, we get 1 with a remainder of 291.
Put 1 as the next digit of the answer. 
Result so far: 2212.168521
Subtracting 629 from 920 leaves us with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Step 14:
When dividing 2910 by 629, we get 4 with a remainder of 394.
The next digit of our result is 4. 
Result so far: 2212.1685214
The remainder is 394 after subtracting 2516 from 2910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Step 15:
3940 divided by 629 is 6 with a remainder of 166.
Record the quotient 6 as the next digit in the result. 
Result so far: 2212.16852146
Deduct 3774 from 3940 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Our division results in 2212.16852146 with a remaining 1.66e-07.
