40957146 ÷ 781 
The aim is to understand the frequency of 781 in 40957146.

On to step 1:
781 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 781

Going ahead to step 2:
If we divide 40 by 781, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Bring next digit (9) of the dividend behind the 40 and repeat the process: 409 / 781

Let's proceed to step 3:
781 goes into 409 0 times with a remainder of 409.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 409 and we're left with 409.
Append the next digit (5) from the dividend to 409 and continue with: 4095 / 781

Let's proceed to step 4:
The number 781 fits into 4095 5 times, leaving a remainder of 190.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 3905 from 4095 and we're left with 190.
Fetch the next digit (7) from the dividend, attach it to 190 and continue: 1907 / 781

Advancing to step 5:
1907 divided by 781 is 2 with a remainder of 345.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we subtract 1562 from 1907, we get 345.
Take the next digit (1) from the dividend and append it to 345, then repeat: 3451 / 781

Advancing to step 6:
If we divide 3451 by 781, we get 4 and a remainder of 327.
The number 4 becomes the next digit in our result. 
Result so far: 524.0
Subtracting 3124 from 3451 leaves us with 327.
Append the next digit (4) from the dividend to 327 and continue with: 3274 / 781

Advancing to step 7:
The number 781 fits into 3274 4 times, leaving a remainder of 150.
Write down 4 as next digit of the result. 
Result so far: 5244.0
If we subtract 3124 from 3274, we get 150.
Take the next digit (6) from the dividend and append it to 150, then repeat: 1506 / 781

Step 8:
The number 781 fits into 1506 1 times, leaving a remainder of 725.
Use 1 as the next digit of our solution. 
Result so far: 52441.0
Deduct 781 from 1506 and we're left with 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Moving on to step 9:
When dividing 7250 by 781, we get 9 with a remainder of 221.
Put 9 as the next digit of the answer. 
Result so far: 52441.9
The remainder is 221 after subtracting 7029 from 7250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 10:
2210 divided by 781 is 2 with a remainder of 648.
Write down 2 as next digit of the result. 
Result so far: 52441.92
Subtract 1562 from 2210 to get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Going ahead to step 11:
If we divide 6480 by 781, we get 8 and a remainder of 232.
Use 8 as the next digit of our solution. 
Result so far: 52441.928
Subtract 6248 from 6480 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 12:
When dividing 2320 by 781, we get 2 with a remainder of 758.
Use 2 as the next digit of our solution. 
Result so far: 52441.9282
Subtract 1562 from 2320 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.

Let's proceed to step 13:
The number 781 fits into 7580 9 times, leaving a remainder of 551.
Use 9 as the next digit of our solution. 
Result so far: 52441.92829
Subtract 7029 from 7580 to get 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Step 14:
781 can be fit into 5510 7 times, resulting in a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 52441.928297
Deduct 5467 from 5510 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 15:
430 divided by 781 is 0 with a remainder of 430.
Use 0 as the next digit of our solution. 
Result so far: 52441.928297
Subtracting 0 from 430 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 16:
4300 divided by 781 is 5 with a remainder of 395.
The next digit of our result is 5. 
Result so far: 52441.92829705
Subtracting 3905 from 4300 leaves us with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

The final result is 52441.92829705 with a remainder of 3.95e-07.
