We divide 19418902 by 401
The aim is to understand the frequency of 401 in 19418902.

Going ahead to step 1:
1 divided by 401 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 401

Going ahead to step 2:
19 divided by 401 is 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 401

Going ahead to step 3:
401 goes into 194 0 times with a remainder of 194.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 194, we get 194.
Append the next digit (1) from the dividend to 194 and continue with: 1941 / 401

Let's proceed to step 4:
When dividing 1941 by 401, we get 4 with a remainder of 337.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 1604 away from 1941, we end up with 337.
Bring next digit (8) of the dividend behind the 337 and repeat the process: 3378 / 401

Step 5:
When dividing 3378 by 401, we get 8 with a remainder of 170.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
If we take 3208 away from 3378, we end up with 170.
Bring next digit (9) of the dividend behind the 170 and repeat the process: 1709 / 401

Let's proceed to step 6:
If we divide 1709 by 401, we get 4 and a remainder of 105.
Write down 4 as next digit of the result. 
Result so far: 484.0
Deduct 1604 from 1709 and we're left with 105.
Take the next digit (0) from the dividend and append it to 105, then repeat: 1050 / 401

Let's proceed to step 7:
The number 401 fits into 1050 2 times, leaving a remainder of 248.
Put 2 as the next digit of the answer. 
Result so far: 4842.0
Deduct 802 from 1050 and we're left with 248.
Append the next digit (2) from the dividend to 248 and continue with: 2482 / 401

Advancing to step 8:
The number 401 fits into 2482 6 times, leaving a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 48426.0
If we subtract 2406 from 2482, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 9:
401 can be fit into 760 1 times, resulting in a remainder of 359.
The next digit of our result is 1. 
Result so far: 48426.1
Subtract 401 from 760 to get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Advancing to step 10:
401 can be fit into 3590 8 times, resulting in a remainder of 382.
Put 8 as the next digit of the answer. 
Result so far: 48426.18
The remainder is 382 after subtracting 3208 from 3590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 11:
When dividing 3820 by 401, we get 9 with a remainder of 211.
Record the quotient 9 as the next digit in the result. 
Result so far: 48426.189
The remainder is 211 after subtracting 3609 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Going ahead to step 12:
2110 divided by 401 is 5 with a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 48426.1895
The remainder is 105 after subtracting 2005 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 13:
401 goes into 1050 2 times with a remainder of 248.
Record the quotient 2 as the next digit in the result. 
Result so far: 48426.18952
If we subtract 802 from 1050, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 14:
401 can be fit into 2480 6 times, resulting in a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 48426.189526
Deduct 2406 from 2480 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 15:
401 goes into 740 1 times with a remainder of 339.
Put 1 as the next digit of the answer. 
Result so far: 48426.1895261
Subtract 401 from 740 to get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Moving on to step 16:
When dividing 3390 by 401, we get 8 with a remainder of 182.
Record the quotient 8 as the next digit in the result. 
Result so far: 48426.18952618
Subtract 3208 from 3390 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

The final outcome is 48426.18952618, with a leftover of 1.82e-07.
