We're dividing 43798880 by 651 
The aim is to understand the frequency of 651 in 43798880.

On to step 1:
When dividing 4 by 651, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 651

Moving on to step 2:
The number 651 fits into 43 0 times, leaving a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Append the next digit (7) from the dividend to 43 and continue with: 437 / 651

Going ahead to step 3:
The number 651 fits into 437 0 times, leaving a remainder of 437.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 437 leaves us with 437.
Grab the next digit (9) from the dividend, add it to 437, then carry on: 4379 / 651

Advancing to step 4:
651 can be fit into 4379 6 times, resulting in a remainder of 473.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 3906 from 4379 and we're left with 473.
Fetch the next digit (8) from the dividend, attach it to 473 and continue: 4738 / 651

Going ahead to step 5:
When dividing 4738 by 651, we get 7 with a remainder of 181.
The next digit of our result is 7. 
Result so far: 67.0
Subtracting 4557 from 4738 leaves us with 181.
Include the next digit (8) from the dividend after 181, then repeat: 1818 / 651

On to step 6:
If we divide 1818 by 651, we get 2 and a remainder of 516.
Write down 2 as next digit of the result. 
Result so far: 672.0
If we subtract 1302 from 1818, we get 516.
Fetch the next digit (8) from the dividend, attach it to 516 and continue: 5168 / 651

Advancing to step 7:
If we divide 5168 by 651, we get 7 and a remainder of 611.
Put 7 as the next digit of the answer. 
Result so far: 6727.0
Subtracting 4557 from 5168 leaves us with 611.
Take the next digit (0) from the dividend and append it to 611, then repeat: 6110 / 651

Moving on to step 8:
651 can be fit into 6110 9 times, resulting in a remainder of 251.
Write down 9 as next digit of the result. 
Result so far: 67279.0
Deduct 5859 from 6110 and we're left with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Advancing to step 9:
651 can be fit into 2510 3 times, resulting in a remainder of 557.
The next digit of our result is 3. 
Result so far: 67279.3
Subtract 1953 from 2510 to get 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Step 10:
651 goes into 5570 8 times with a remainder of 362.
Record the quotient 8 as the next digit in the result. 
Result so far: 67279.38
The remainder is 362 after subtracting 5208 from 5570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Going ahead to step 11:
651 goes into 3620 5 times with a remainder of 365.
Write down 5 as next digit of the result. 
Result so far: 67279.385
Subtracting 3255 from 3620 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Advancing to step 12:
3650 divided by 651 is 5 with a remainder of 395.
Put 5 as the next digit of the answer. 
Result so far: 67279.3855
Subtract 3255 from 3650 to get 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 quotient of the division is 67279.3855, and the remainder is 0.00395.
