We're dividing 81761945 by 957 
The aim is to understand the frequency of 957 in 81761945.

Going ahead to step 1:
8 divided by 957 is 0 with 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 (1) from the dividend, add it to 8, then carry on: 81 / 957

Let's proceed to step 2:
957 goes into 81 0 times with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Include the next digit (7) from the dividend after 81, then repeat: 817 / 957

Let's proceed to step 3:
When dividing 817 by 957, we get 0 with a remainder of 817.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 817, we get 817.
Bring next digit (6) of the dividend behind the 817 and repeat the process: 8176 / 957

Advancing to step 4:
8176 divided by 957 is 8 with a remainder of 520.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 7656 away from 8176, we end up with 520.
Include the next digit (1) from the dividend after 520, then repeat: 5201 / 957

Moving on to step 5:
The number 957 fits into 5201 5 times, leaving a remainder of 416.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
If we subtract 4785 from 5201, we get 416.
Include the next digit (9) from the dividend after 416, then repeat: 4169 / 957

Going ahead to step 6:
957 can be fit into 4169 4 times, resulting in a remainder of 341.
Use 4 as the next digit of our solution. 
Result so far: 854.0
Deduct 3828 from 4169 and we're left with 341.
Take the next digit (4) from the dividend and append it to 341, then repeat: 3414 / 957

Let's proceed to step 7:
3414 divided by 957 is 3 with a remainder of 543.
Put 3 as the next digit of the answer. 
Result so far: 8543.0
Subtract 2871 from 3414 to get 543.
Grab the next digit (5) from the dividend, add it to 543, then carry on: 5435 / 957

On to step 8:
957 can be fit into 5435 5 times, resulting in a remainder of 650.
The next digit of our result is 5. 
Result so far: 85435.0
The remainder is 650 after subtracting 4785 from 5435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 9:
957 can be fit into 6500 6 times, resulting in a remainder of 758.
Put 6 as the next digit of the answer. 
Result so far: 85435.6
Subtract 5742 from 6500 to get 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

Going ahead to step 10:
If we divide 7580 by 957, we get 7 and a remainder of 881.
Write down 7 as next digit of the result. 
Result so far: 85435.67
If we take 6699 away from 7580, we end up with 881.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8810, and continue the process.

Going ahead to step 11:
957 can be fit into 8810 9 times, resulting in a remainder of 197.
Write down 9 as next digit of the result. 
Result so far: 85435.679
The remainder is 197 after subtracting 8613 from 8810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Moving on to step 12:
When dividing 1970 by 957, we get 2 with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 85435.6792
If we take 1914 away from 1970, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
957 goes into 560 0 times with a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 85435.6792
Subtracting 0 from 560 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 14:
5600 divided by 957 is 5 with a remainder of 815.
The next digit of our result is 5. 
Result so far: 85435.679205
If we subtract 4785 from 5600, we get 815.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8150, and continue the process.

Moving on to step 15:
957 goes into 8150 8 times with a remainder of 494.
Record the quotient 8 as the next digit in the result. 
Result so far: 85435.6792058
The remainder is 494 after subtracting 7656 from 8150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

On to step 16:
957 goes into 4940 5 times with a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 85435.67920585
Deduct 4785 from 4940 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

The quotient of the division is 85435.67920585, and the remainder is 1.55e-07.
