We look at the division of 70385838 by 657 
The aim is to understand the frequency of 657 in 70385838.

On to step 1:
657 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 657

Step 2:
70 divided by 657 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 657

Moving on to step 3:
657 can be fit into 703 1 times, resulting in a remainder of 46.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 657 from 703 and we're left with 46.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 657

Let's proceed to step 4:
The number 657 fits into 468 0 times, leaving a remainder of 468.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 468 and we're left with 468.
Fetch the next digit (5) from the dividend, attach it to 468 and continue: 4685 / 657

Let's proceed to step 5:
When dividing 4685 by 657, we get 7 with a remainder of 86.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Subtracting 4599 from 4685 leaves us with 86.
Append the next digit (8) from the dividend to 86 and continue with: 868 / 657

On to step 6:
If we divide 868 by 657, we get 1 and a remainder of 211.
The next digit of our result is 1. 
Result so far: 1071.0
The remainder is 211 after subtracting 657 from 868.
Grab the next digit (3) from the dividend, add it to 211, then carry on: 2113 / 657

Going ahead to step 7:
The number 657 fits into 2113 3 times, leaving a remainder of 142.
The number 3 becomes the next digit in our result. 
Result so far: 10713.0
The remainder is 142 after subtracting 1971 from 2113.
Append the next digit (8) from the dividend to 142 and continue with: 1428 / 657

Let's proceed to step 8:
The number 657 fits into 1428 2 times, leaving a remainder of 114.
The next digit of our result is 2. 
Result so far: 107132.0
Subtract 1314 from 1428 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 9:
If we divide 1140 by 657, we get 1 and a remainder of 483.
Record the quotient 1 as the next digit in the result. 
Result so far: 107132.1
If we subtract 657 from 1140, we get 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Moving on to step 10:
When dividing 4830 by 657, we get 7 with a remainder of 231.
Use 7 as the next digit of our solution. 
Result so far: 107132.17
Deduct 4599 from 4830 and we're left with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 11:
If we divide 2310 by 657, we get 3 and a remainder of 339.
Put 3 as the next digit of the answer. 
Result so far: 107132.173
If we take 1971 away from 2310, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Let's proceed to step 12:
657 can be fit into 3390 5 times, resulting in a remainder of 105.
The next digit of our result is 5. 
Result so far: 107132.1735
If we take 3285 away from 3390, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 13:
When dividing 1050 by 657, we get 1 with a remainder of 393.
The number 1 becomes the next digit in our result. 
Result so far: 107132.17351
Deduct 657 from 1050 and we're left with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Step 14:
3930 divided by 657 is 5 with a remainder of 645.
Write down 5 as next digit of the result. 
Result so far: 107132.173515
If we take 3285 away from 3930, we end up with 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Let's proceed to step 15:
657 goes into 6450 9 times with a remainder of 537.
Use 9 as the next digit of our solution. 
Result so far: 107132.1735159
Deduct 5913 from 6450 and we're left with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Moving on to step 16:
657 can be fit into 5370 8 times, resulting in a remainder of 114.
Put 8 as the next digit of the answer. 
Result so far: 107132.17351598
The remainder is 114 after subtracting 5256 from 5370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

In conclusion, the division gives 107132.17351598 with a balance of 1.14e-07.
