45379429 divided by 801 
The aim is to understand the frequency of 801 in 45379429.

Going ahead to step 1:
801 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 801

Moving on to step 2:
45 divided by 801 is 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Take the next digit (3) from the dividend and append it to 45, then repeat: 453 / 801

Going ahead to step 3:
The number 801 fits into 453 0 times, leaving a remainder of 453.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 453 after subtracting 0 from 453.
Include the next digit (7) from the dividend after 453, then repeat: 4537 / 801

Let's proceed to step 4:
801 can be fit into 4537 5 times, resulting in a remainder of 532.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 4005 from 4537 to get 532.
Grab the next digit (9) from the dividend, add it to 532, then carry on: 5329 / 801

Step 5:
801 can be fit into 5329 6 times, resulting in a remainder of 523.
Put 6 as the next digit of the answer. 
Result so far: 56.0
Deduct 4806 from 5329 and we're left with 523.
Take the next digit (4) from the dividend and append it to 523, then repeat: 5234 / 801

Advancing to step 6:
5234 divided by 801 is 6 with a remainder of 428.
Record the quotient 6 as the next digit in the result. 
Result so far: 566.0
Deduct 4806 from 5234 and we're left with 428.
Grab the next digit (2) from the dividend, add it to 428, then carry on: 4282 / 801

Advancing to step 7:
801 can be fit into 4282 5 times, resulting in a remainder of 277.
The number 5 becomes the next digit in our result. 
Result so far: 5665.0
Subtracting 4005 from 4282 leaves us with 277.
Append the next digit (9) from the dividend to 277 and continue with: 2779 / 801

Let's proceed to step 8:
801 can be fit into 2779 3 times, resulting in a remainder of 376.
Use 3 as the next digit of our solution. 
Result so far: 56653.0
The remainder is 376 after subtracting 2403 from 2779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 9:
801 goes into 3760 4 times with a remainder of 556.
Record the quotient 4 as the next digit in the result. 
Result so far: 56653.4
Subtracting 3204 from 3760 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Let's proceed to step 10:
When dividing 5560 by 801, we get 6 with a remainder of 754.
The next digit of our result is 6. 
Result so far: 56653.46
Deduct 4806 from 5560 and we're left with 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Going ahead to step 11:
7540 divided by 801 is 9 with a remainder of 331.
The number 9 becomes the next digit in our result. 
Result so far: 56653.469
If we take 7209 away from 7540, we end up with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Going ahead to step 12:
3310 divided by 801 is 4 with a remainder of 106.
Put 4 as the next digit of the answer. 
Result so far: 56653.4694
If we subtract 3204 from 3310, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 13:
If we divide 1060 by 801, we get 1 and a remainder of 259.
Record the quotient 1 as the next digit in the result. 
Result so far: 56653.46941
If we take 801 away from 1060, we end up with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Step 14:
If we divide 2590 by 801, we get 3 and a remainder of 187.
Use 3 as the next digit of our solution. 
Result so far: 56653.469413
If we take 2403 away from 2590, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Step 15:
801 can be fit into 1870 2 times, resulting in a remainder of 268.
The next digit of our result is 2. 
Result so far: 56653.4694132
Subtracting 1602 from 1870 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 16:
If we divide 2680 by 801, we get 3 and a remainder of 277.
The number 3 becomes the next digit in our result. 
Result so far: 56653.46941323
The remainder is 277 after subtracting 2403 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

The final outcome is 56653.46941323, with a leftover of 2.77e-07.
