51977066 ÷ 436 
The aim is to understand the frequency of 436 in 51977066.

Advancing to step 1:
5 divided by 436 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
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 / 436

Step 2:
If we divide 51 by 436, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 436

Step 3:
If we divide 519 by 436, we get 1 and a remainder of 83.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 436 from 519 to get 83.
Bring next digit (7) of the dividend behind the 83 and repeat the process: 837 / 436

On to step 4:
The number 436 fits into 837 1 times, leaving a remainder of 401.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 401 after subtracting 436 from 837.
Take the next digit (7) from the dividend and append it to 401, then repeat: 4017 / 436

Advancing to step 5:
436 can be fit into 4017 9 times, resulting in a remainder of 93.
Put 9 as the next digit of the answer. 
Result so far: 119.0
If we take 3924 away from 4017, we end up with 93.
Take the next digit (0) from the dividend and append it to 93, then repeat: 930 / 436

Let's proceed to step 6:
436 can be fit into 930 2 times, resulting in a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 1192.0
Subtract 872 from 930 to get 58.
Take the next digit (6) from the dividend and append it to 58, then repeat: 586 / 436

Let's proceed to step 7:
436 goes into 586 1 times with a remainder of 150.
Use 1 as the next digit of our solution. 
Result so far: 11921.0
If we subtract 436 from 586, we get 150.
Bring next digit (6) of the dividend behind the 150 and repeat the process: 1506 / 436

Advancing to step 8:
If we divide 1506 by 436, we get 3 and a remainder of 198.
The number 3 becomes the next digit in our result. 
Result so far: 119213.0
Deduct 1308 from 1506 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 9:
The number 436 fits into 1980 4 times, leaving a remainder of 236.
The next digit of our result is 4. 
Result so far: 119213.4
Deduct 1744 from 1980 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 10:
436 can be fit into 2360 5 times, resulting in a remainder of 180.
Use 5 as the next digit of our solution. 
Result so far: 119213.45
If we take 2180 away from 2360, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
1800 divided by 436 is 4 with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 119213.454
Deduct 1744 from 1800 and we're left 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 12:
If we divide 560 by 436, we get 1 and a remainder of 124.
Use 1 as the next digit of our solution. 
Result so far: 119213.4541
The remainder is 124 after subtracting 436 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 13:
If we divide 1240 by 436, we get 2 and a remainder of 368.
The number 2 becomes the next digit in our result. 
Result so far: 119213.45412
If we subtract 872 from 1240, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 14:
The number 436 fits into 3680 8 times, leaving a remainder of 192.
Use 8 as the next digit of our solution. 
Result so far: 119213.454128
The remainder is 192 after subtracting 3488 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 15:
436 can be fit into 1920 4 times, resulting in a remainder of 176.
The next digit of our result is 4. 
Result so far: 119213.4541284
Subtract 1744 from 1920 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 16:
436 can be fit into 1760 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 119213.45412844
If we take 1744 away from 1760, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 119213.45412844 and a remainder of 1.6e-08.
