70210661 ÷ 959 
The aim is to understand the frequency of 959 in 70210661.

Advancing to step 1:
959 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 959

Step 2:
959 can be fit into 70 0 times, resulting in a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Fetch the next digit (2) from the dividend, attach it to 70 and continue: 702 / 959

Step 3:
959 can be fit into 702 0 times, resulting in a remainder of 702.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 702 to get 702.
Bring next digit (1) of the dividend behind the 702 and repeat the process: 7021 / 959

On to step 4:
959 can be fit into 7021 7 times, resulting in a remainder of 308.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 6713 from 7021 and we're left with 308.
Take the next digit (0) from the dividend and append it to 308, then repeat: 3080 / 959

Going ahead to step 5:
959 can be fit into 3080 3 times, resulting in a remainder of 203.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
If we take 2877 away from 3080, we end up with 203.
Fetch the next digit (6) from the dividend, attach it to 203 and continue: 2036 / 959

Step 6:
959 goes into 2036 2 times with a remainder of 118.
Put 2 as the next digit of the answer. 
Result so far: 732.0
The remainder is 118 after subtracting 1918 from 2036.
Include the next digit (6) from the dividend after 118, then repeat: 1186 / 959

Moving on to step 7:
959 goes into 1186 1 times with a remainder of 227.
The next digit of our result is 1. 
Result so far: 7321.0
If we subtract 959 from 1186, we get 227.
Take the next digit (1) from the dividend and append it to 227, then repeat: 2271 / 959

Let's proceed to step 8:
2271 divided by 959 is 2 with a remainder of 353.
The next digit of our result is 2. 
Result so far: 73212.0
The remainder is 353 after subtracting 1918 from 2271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Moving on to step 9:
3530 divided by 959 is 3 with a remainder of 653.
Put 3 as the next digit of the answer. 
Result so far: 73212.3
Deduct 2877 from 3530 and we're left with 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

On to step 10:
If we divide 6530 by 959, we get 6 and a remainder of 776.
Put 6 as the next digit of the answer. 
Result so far: 73212.36
Subtracting 5754 from 6530 leaves us with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Step 11:
If we divide 7760 by 959, we get 8 and a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 73212.368
The remainder is 88 after subtracting 7672 from 7760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 12:
If we divide 880 by 959, we get 0 and a remainder of 880.
The next digit of our result is 0. 
Result so far: 73212.368
Subtracting 0 from 880 leaves us with 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

Step 13:
When dividing 8800 by 959, we get 9 with a remainder of 169.
Write down 9 as next digit of the result. 
Result so far: 73212.36809
If we subtract 8631 from 8800, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Moving on to step 14:
1690 divided by 959 is 1 with a remainder of 731.
Record the quotient 1 as the next digit in the result. 
Result so far: 73212.368091
If we subtract 959 from 1690, we get 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

Let's proceed to step 15:
When dividing 7310 by 959, we get 7 with a remainder of 597.
Use 7 as the next digit of our solution. 
Result so far: 73212.3680917
If we subtract 6713 from 7310, we get 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Moving on to step 16:
When dividing 5970 by 959, we get 6 with a remainder of 216.
Use 6 as the next digit of our solution. 
Result so far: 73212.36809176
The remainder is 216 after subtracting 5754 from 5970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

In conclusion, the division gives 73212.36809176 with a balance of 2.16e-07.
