74337130 divided by 401 
The aim is to understand the frequency of 401 in 74337130.

Going ahead to step 1:
401 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 401

Going ahead to step 2:
74 divided by 401 is 0 with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Include the next digit (3) from the dividend after 74, then repeat: 743 / 401

Advancing to step 3:
401 goes into 743 1 times with a remainder of 342.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 401 from 743 and we're left with 342.
Take the next digit (3) from the dividend and append it to 342, then repeat: 3423 / 401

Moving on to step 4:
When dividing 3423 by 401, we get 8 with a remainder of 215.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 3208 from 3423 leaves us with 215.
Bring next digit (7) of the dividend behind the 215 and repeat the process: 2157 / 401

Step 5:
401 goes into 2157 5 times with a remainder of 152.
The number 5 becomes the next digit in our result. 
Result so far: 185.0
If we take 2005 away from 2157, we end up with 152.
Fetch the next digit (1) from the dividend, attach it to 152 and continue: 1521 / 401

Let's proceed to step 6:
401 can be fit into 1521 3 times, resulting in a remainder of 318.
Put 3 as the next digit of the answer. 
Result so far: 1853.0
Subtracting 1203 from 1521 leaves us with 318.
Grab the next digit (3) from the dividend, add it to 318, then carry on: 3183 / 401

Going ahead to step 7:
When dividing 3183 by 401, we get 7 with a remainder of 376.
Put 7 as the next digit of the answer. 
Result so far: 18537.0
Subtract 2807 from 3183 to get 376.
Grab the next digit (0) from the dividend, add it to 376, then carry on: 3760 / 401

Let's proceed to step 8:
401 goes into 3760 9 times with a remainder of 151.
The number 9 becomes the next digit in our result. 
Result so far: 185379.0
If we take 3609 away from 3760, we end up with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

On to step 9:
If we divide 1510 by 401, we get 3 and a remainder of 307.
Record the quotient 3 as the next digit in the result. 
Result so far: 185379.3
If we take 1203 away from 1510, we end up 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.

Advancing to step 10:
When dividing 3070 by 401, we get 7 with a remainder of 263.
Use 7 as the next digit of our solution. 
Result so far: 185379.37
Subtracting 2807 from 3070 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Moving on to step 11:
401 goes into 2630 6 times with a remainder of 224.
Write down 6 as next digit of the result. 
Result so far: 185379.376
If we take 2406 away from 2630, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 12:
The number 401 fits into 2240 5 times, leaving a remainder of 235.
The next digit of our result is 5. 
Result so far: 185379.3765
Subtract 2005 from 2240 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

On to step 13:
If we divide 2350 by 401, we get 5 and a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 185379.37655
If we take 2005 away from 2350, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

The final outcome is 185379.37655, with a leftover of 0.000345.
