89890493 ÷ 629 
The aim is to understand the frequency of 629 in 89890493.

Moving on to step 1:
629 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 629

Advancing to step 2:
When dividing 89 by 629, we get 0 with a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Bring next digit (8) of the dividend behind the 89 and repeat the process: 898 / 629

Going ahead to step 3:
The number 629 fits into 898 1 times, leaving a remainder of 269.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 629 from 898 and we're left with 269.
Take the next digit (9) from the dividend and append it to 269, then repeat: 2699 / 629

Let's proceed to step 4:
629 goes into 2699 4 times with a remainder of 183.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 183 after subtracting 2516 from 2699.
Bring next digit (0) of the dividend behind the 183 and repeat the process: 1830 / 629

Moving on to step 5:
When dividing 1830 by 629, we get 2 with a remainder of 572.
Use 2 as the next digit of our solution. 
Result so far: 142.0
If we subtract 1258 from 1830, we get 572.
Append the next digit (4) from the dividend to 572 and continue with: 5724 / 629

Moving on to step 6:
If we divide 5724 by 629, we get 9 and a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 1429.0
If we take 5661 away from 5724, we end up with 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 629

Moving on to step 7:
When dividing 639 by 629, we get 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 14291.0
The remainder is 10 after subtracting 629 from 639.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 629

Moving on to step 8:
629 can be fit into 103 0 times, resulting in a remainder of 103.
Use 0 as the next digit of our solution. 
Result so far: 142910.0
The remainder is 103 after subtracting 0 from 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 9:
If we divide 1030 by 629, we get 1 and a remainder of 401.
The next digit of our result is 1. 
Result so far: 142910.1
Deduct 629 from 1030 and we're left with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Advancing to step 10:
The number 629 fits into 4010 6 times, leaving a remainder of 236.
Write down 6 as next digit of the result. 
Result so far: 142910.16
If we take 3774 away from 4010, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 11:
When dividing 2360 by 629, we get 3 with a remainder of 473.
The next digit of our result is 3. 
Result so far: 142910.163
The remainder is 473 after subtracting 1887 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Let's proceed to step 12:
629 goes into 4730 7 times with a remainder of 327.
Use 7 as the next digit of our solution. 
Result so far: 142910.1637
Deduct 4403 from 4730 and we're left with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Let's proceed to step 13:
If we divide 3270 by 629, we get 5 and a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 142910.16375
Subtracting 3145 from 3270 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 14:
629 goes into 1250 1 times with a remainder of 621.
Put 1 as the next digit of the answer. 
Result so far: 142910.163751
If we subtract 629 from 1250, we get 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

Going ahead to step 15:
The number 629 fits into 6210 9 times, leaving a remainder of 549.
Use 9 as the next digit of our solution. 
Result so far: 142910.1637519
Deduct 5661 from 6210 and we're left with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Going ahead to step 16:
5490 divided by 629 is 8 with a remainder of 458.
Use 8 as the next digit of our solution. 
Result so far: 142910.16375198
Subtracting 5032 from 5490 leaves us with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

After the division, we end up with 142910.16375198 and a remainder of 4.58e-07.
