We divide 90710427 by 126
The aim is to understand the frequency of 126 in 90710427.

Let's proceed to step 1:
If we divide 9 by 126, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 126

Moving on to step 2:
If we divide 90 by 126, we get 0 and a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Append the next digit (7) from the dividend to 90 and continue with: 907 / 126

Going ahead to step 3:
907 divided by 126 is 7 with a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 882 away from 907, we end up with 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 126

Step 4:
When dividing 251 by 126, we get 1 with a remainder of 125.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
The remainder is 125 after subtracting 126 from 251.
Take the next digit (0) from the dividend and append it to 125, then repeat: 1250 / 126

Advancing to step 5:
The number 126 fits into 1250 9 times, leaving a remainder of 116.
The number 9 becomes the next digit in our result. 
Result so far: 719.0
The remainder is 116 after subtracting 1134 from 1250.
Bring next digit (4) of the dividend behind the 116 and repeat the process: 1164 / 126

Going ahead to step 6:
The number 126 fits into 1164 9 times, leaving a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 7199.0
If we subtract 1134 from 1164, we get 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 126

Going ahead to step 7:
126 can be fit into 302 2 times, resulting in a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 71992.0
Subtract 252 from 302 to get 50.
Append the next digit (7) from the dividend to 50 and continue with: 507 / 126

Step 8:
The number 126 fits into 507 4 times, leaving a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 719924.0
If we subtract 504 from 507, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
126 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 719924.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
126 goes into 300 2 times with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 719924.02
Subtract 252 from 300 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
126 goes into 480 3 times with a remainder of 102.
Record the quotient 3 as the next digit in the result. 
Result so far: 719924.023
If we take 378 away from 480, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 12:
1020 divided by 126 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 719924.0238
If we subtract 1008 from 1020, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
126 can be fit into 120 0 times, resulting in a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 719924.0238
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 14:
When dividing 1200 by 126, we get 9 with a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 719924.023809
Deduct 1134 from 1200 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 15:
When dividing 660 by 126, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 719924.0238095
Subtract 630 from 660 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 16:
126 can be fit into 300 2 times, resulting in a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 719924.02380952
The remainder is 48 after subtracting 252 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 719924.02380952 with a remaining 4.8e-08.
