1253811 ÷ 957 
The aim is to understand the frequency of 957 in 1253811.

Let's proceed to step 1:
1 divided by 957 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 957

On to step 2:
957 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 957

Step 3:
The number 957 fits into 125 0 times, leaving a remainder of 125.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 125 after subtracting 0 from 125.
Append the next digit (3) from the dividend to 125 and continue with: 1253 / 957

Let's proceed to step 4:
The number 957 fits into 1253 1 times, leaving a remainder of 296.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 296 after subtracting 957 from 1253.
Take the next digit (8) from the dividend and append it to 296, then repeat: 2968 / 957

Let's proceed to step 5:
When dividing 2968 by 957, we get 3 with a remainder of 97.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 2871 from 2968 and we're left with 97.
Grab the next digit (1) from the dividend, add it to 97, then carry on: 971 / 957

Advancing to step 6:
971 divided by 957 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
The remainder is 14 after subtracting 957 from 971.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 957

Advancing to step 7:
When dividing 141 by 957, we get 0 with a remainder of 141.
Use 0 as the next digit of our solution. 
Result so far: 1310.0
Subtract 0 from 141 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 8:
When dividing 1410 by 957, we get 1 with a remainder of 453.
Put 1 as the next digit of the answer. 
Result so far: 1310.1
Deduct 957 from 1410 and we're left with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Advancing to step 9:
The number 957 fits into 4530 4 times, leaving a remainder of 702.
The next digit of our result is 4. 
Result so far: 1310.14
If we subtract 3828 from 4530, we get 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Step 10:
7020 divided by 957 is 7 with a remainder of 321.
Record the quotient 7 as the next digit in the result. 
Result so far: 1310.147
The remainder is 321 after subtracting 6699 from 7020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Advancing to step 11:
If we divide 3210 by 957, we get 3 and a remainder of 339.
The next digit of our result is 3. 
Result so far: 1310.1473
Subtract 2871 from 3210 to get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Going ahead to step 12:
957 can be fit into 3390 3 times, resulting in a remainder of 519.
Record the quotient 3 as the next digit in the result. 
Result so far: 1310.14733
Deduct 2871 from 3390 and we're left with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

The final outcome is 1310.14733, with a leftover of 0.000519.
