43554516 ÷ 806 
The aim is to understand the frequency of 806 in 43554516.

Advancing to step 1:
If we divide 4 by 806, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 806

Going ahead to step 2:
806 goes into 43 0 times with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Append the next digit (5) from the dividend to 43 and continue with: 435 / 806

Let's proceed to step 3:
The number 806 fits into 435 0 times, leaving a remainder of 435.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 435 to get 435.
Fetch the next digit (5) from the dividend, attach it to 435 and continue: 4355 / 806

Advancing to step 4:
When dividing 4355 by 806, we get 5 with a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 4030 away from 4355, we end up with 325.
Take the next digit (4) from the dividend and append it to 325, then repeat: 3254 / 806

Moving on to step 5:
806 goes into 3254 4 times with a remainder of 30.
The next digit of our result is 4. 
Result so far: 54.0
If we subtract 3224 from 3254, we get 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 806

Moving on to step 6:
The number 806 fits into 305 0 times, leaving a remainder of 305.
Record the quotient 0 as the next digit in the result. 
Result so far: 540.0
If we subtract 0 from 305, we get 305.
Append the next digit (1) from the dividend to 305 and continue with: 3051 / 806

On to step 7:
806 goes into 3051 3 times with a remainder of 633.
Record the quotient 3 as the next digit in the result. 
Result so far: 5403.0
Subtract 2418 from 3051 to get 633.
Take the next digit (6) from the dividend and append it to 633, then repeat: 6336 / 806

Advancing to step 8:
806 goes into 6336 7 times with a remainder of 694.
The next digit of our result is 7. 
Result so far: 54037.0
If we subtract 5642 from 6336, we get 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Let's proceed to step 9:
If we divide 6940 by 806, we get 8 and a remainder of 492.
Record the quotient 8 as the next digit in the result. 
Result so far: 54037.8
If we take 6448 away from 6940, we end up with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Moving on to step 10:
When dividing 4920 by 806, we get 6 with a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 54037.86
If we take 4836 away from 4920, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 11:
If we divide 840 by 806, we get 1 and a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 54037.861
If we take 806 away from 840, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 12:
340 divided by 806 is 0 with a remainder of 340.
Put 0 as the next digit of the answer. 
Result so far: 54037.861
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 13:
806 can be fit into 3400 4 times, resulting in a remainder of 176.
Write down 4 as next digit of the result. 
Result so far: 54037.86104
Deduct 3224 from 3400 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 14:
If we divide 1760 by 806, we get 2 and a remainder of 148.
Write down 2 as next digit of the result. 
Result so far: 54037.861042
Subtract 1612 from 1760 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 15:
If we divide 1480 by 806, we get 1 and a remainder of 674.
Record the quotient 1 as the next digit in the result. 
Result so far: 54037.8610421
Subtract 806 from 1480 to get 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Going ahead to step 16:
If we divide 6740 by 806, we get 8 and a remainder of 292.
Use 8 as the next digit of our solution. 
Result so far: 54037.86104218
If we take 6448 away from 6740, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

In conclusion, the division gives 54037.86104218 with a balance of 2.92e-07.
