We're dividing 38898813 by 901 
The aim is to understand the frequency of 901 in 38898813.

On to step 1:
The number 901 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 901

Going ahead to step 2:
If we divide 38 by 901, we get 0 and a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 901

On to step 3:
388 divided by 901 is 0 with a remainder of 388.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 388 and we're left with 388.
Take the next digit (9) from the dividend and append it to 388, then repeat: 3889 / 901

Going ahead to step 4:
901 goes into 3889 4 times with a remainder of 285.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 3604 from 3889 and we're left with 285.
Bring next digit (8) of the dividend behind the 285 and repeat the process: 2858 / 901

Advancing to step 5:
2858 divided by 901 is 3 with a remainder of 155.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
The remainder is 155 after subtracting 2703 from 2858.
Append the next digit (8) from the dividend to 155 and continue with: 1558 / 901

Moving on to step 6:
When dividing 1558 by 901, we get 1 with a remainder of 657.
Use 1 as the next digit of our solution. 
Result so far: 431.0
Deduct 901 from 1558 and we're left with 657.
Grab the next digit (1) from the dividend, add it to 657, then carry on: 6571 / 901

Going ahead to step 7:
901 goes into 6571 7 times with a remainder of 264.
Put 7 as the next digit of the answer. 
Result so far: 4317.0
The remainder is 264 after subtracting 6307 from 6571.
Fetch the next digit (3) from the dividend, attach it to 264 and continue: 2643 / 901

On to step 8:
The number 901 fits into 2643 2 times, leaving a remainder of 841.
Use 2 as the next digit of our solution. 
Result so far: 43172.0
If we take 1802 away from 2643, we end up with 841.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8410, and continue the process.

Moving on to step 9:
The number 901 fits into 8410 9 times, leaving a remainder of 301.
Use 9 as the next digit of our solution. 
Result so far: 43172.9
Deduct 8109 from 8410 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 10:
When dividing 3010 by 901, we get 3 with a remainder of 307.
Use 3 as the next digit of our solution. 
Result so far: 43172.93
Deduct 2703 from 3010 and we're left with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Going ahead to step 11:
The number 901 fits into 3070 3 times, leaving a remainder of 367.
Write down 3 as next digit of the result. 
Result so far: 43172.933
Deduct 2703 from 3070 and we're left with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Our division results in 43172.933 with a remaining 0.0367.
