51141091 ÷ 783 
The aim is to understand the frequency of 783 in 51141091.

On to step 1:
When dividing 5 by 783, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 783

Moving on to step 2:
When dividing 51 by 783, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (1) from the dividend, attach it to 51 and continue: 511 / 783

Moving on to step 3:
511 divided by 783 is 0 with a remainder of 511.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 511 and we're left with 511.
Include the next digit (4) from the dividend after 511, then repeat: 5114 / 783

Going ahead to step 4:
783 can be fit into 5114 6 times, resulting in a remainder of 416.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 4698 from 5114 and we're left with 416.
Include the next digit (1) from the dividend after 416, then repeat: 4161 / 783

Moving on to step 5:
783 can be fit into 4161 5 times, resulting in a remainder of 246.
The next digit of our result is 5. 
Result so far: 65.0
The remainder is 246 after subtracting 3915 from 4161.
Fetch the next digit (0) from the dividend, attach it to 246 and continue: 2460 / 783

On to step 6:
When dividing 2460 by 783, we get 3 with a remainder of 111.
Use 3 as the next digit of our solution. 
Result so far: 653.0
Subtract 2349 from 2460 to get 111.
Fetch the next digit (9) from the dividend, attach it to 111 and continue: 1119 / 783

Moving on to step 7:
783 can be fit into 1119 1 times, resulting in a remainder of 336.
Put 1 as the next digit of the answer. 
Result so far: 6531.0
If we subtract 783 from 1119, we get 336.
Take the next digit (1) from the dividend and append it to 336, then repeat: 3361 / 783

On to step 8:
783 goes into 3361 4 times with a remainder of 229.
Record the quotient 4 as the next digit in the result. 
Result so far: 65314.0
The remainder is 229 after subtracting 3132 from 3361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Advancing to step 9:
2290 divided by 783 is 2 with a remainder of 724.
The next digit of our result is 2. 
Result so far: 65314.2
Subtracting 1566 from 2290 leaves us with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

On to step 10:
If we divide 7240 by 783, we get 9 and a remainder of 193.
The number 9 becomes the next digit in our result. 
Result so far: 65314.29
If we subtract 7047 from 7240, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Moving on to step 11:
783 can be fit into 1930 2 times, resulting in a remainder of 364.
Record the quotient 2 as the next digit in the result. 
Result so far: 65314.292
Deduct 1566 from 1930 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 12:
The number 783 fits into 3640 4 times, leaving a remainder of 508.
Put 4 as the next digit of the answer. 
Result so far: 65314.2924
Deduct 3132 from 3640 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

On to step 13:
If we divide 5080 by 783, we get 6 and a remainder of 382.
The next digit of our result is 6. 
Result so far: 65314.29246
If we take 4698 away from 5080, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Let's proceed to step 14:
783 can be fit into 3820 4 times, resulting in a remainder of 688.
The number 4 becomes the next digit in our result. 
Result so far: 65314.292464
The remainder is 688 after subtracting 3132 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Step 15:
When dividing 6880 by 783, we get 8 with a remainder of 616.
Write down 8 as next digit of the result. 
Result so far: 65314.2924648
Subtracting 6264 from 6880 leaves us with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 16:
6160 divided by 783 is 7 with a remainder of 679.
Write down 7 as next digit of the result. 
Result so far: 65314.29246487
Deduct 5481 from 6160 and we're left with 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

The quotient of the division is 65314.29246487, and the remainder is 6.79e-07.
