71394830 divided by 126 
The aim is to understand the frequency of 126 in 71394830.

On to step 1:
126 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 126

Let's proceed to step 2:
126 goes into 71 0 times with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Grab the next digit (3) from the dividend, add it to 71, then carry on: 713 / 126

Advancing to step 3:
When dividing 713 by 126, we get 5 with a remainder of 83.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 630 from 713, we get 83.
Fetch the next digit (9) from the dividend, attach it to 83 and continue: 839 / 126

Going ahead to step 4:
When dividing 839 by 126, we get 6 with a remainder of 83.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
If we subtract 756 from 839, we get 83.
Grab the next digit (4) from the dividend, add it to 83, then carry on: 834 / 126

Going ahead to step 5:
126 goes into 834 6 times with a remainder of 78.
Use 6 as the next digit of our solution. 
Result so far: 566.0
Subtract 756 from 834 to get 78.
Fetch the next digit (8) from the dividend, attach it to 78 and continue: 788 / 126

Going ahead to step 6:
126 goes into 788 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 5666.0
If we subtract 756 from 788, we get 32.
Fetch the next digit (3) from the dividend, attach it to 32 and continue: 323 / 126

Going ahead to step 7:
When dividing 323 by 126, we get 2 with a remainder of 71.
The next digit of our result is 2. 
Result so far: 56662.0
If we subtract 252 from 323, we get 71.
Bring next digit (0) of the dividend behind the 71 and repeat the process: 710 / 126

Moving on to step 8:
126 goes into 710 5 times with a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 566625.0
Deduct 630 from 710 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 9:
126 goes into 800 6 times with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 566625.6
Deduct 756 from 800 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
If we divide 440 by 126, we get 3 and a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 566625.63
Subtracting 378 from 440 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 11:
126 can be fit into 620 4 times, resulting in a remainder of 116.
The next digit of our result is 4. 
Result so far: 566625.634
If we subtract 504 from 620, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 12:
126 can be fit into 1160 9 times, resulting in a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 566625.6349
If we subtract 1134 from 1160, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 13:
When dividing 260 by 126, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 566625.63492
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
If we divide 80 by 126, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 566625.63492
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 15:
When dividing 800 by 126, we get 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 566625.6349206
Deduct 756 from 800 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 16:
440 divided by 126 is 3 with a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 566625.63492063
If we take 378 away from 440, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final result is 566625.63492063 with a remainder of 6.2e-08.
