57051057 divided by 401 
The aim is to understand the frequency of 401 in 57051057.

Advancing to step 1:
When dividing 5 by 401, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 401

Step 2:
401 can be fit into 57 0 times, resulting in a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Bring next digit (0) of the dividend behind the 57 and repeat the process: 570 / 401

Advancing to step 3:
570 divided by 401 is 1 with a remainder of 169.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 401 from 570 and we're left with 169.
Fetch the next digit (5) from the dividend, attach it to 169 and continue: 1695 / 401

Going ahead to step 4:
401 can be fit into 1695 4 times, resulting in a remainder of 91.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 1604 from 1695 and we're left with 91.
Append the next digit (1) from the dividend to 91 and continue with: 911 / 401

Going ahead to step 5:
When dividing 911 by 401, we get 2 with a remainder of 109.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
Deduct 802 from 911 and we're left with 109.
Grab the next digit (0) from the dividend, add it to 109, then carry on: 1090 / 401

On to step 6:
The number 401 fits into 1090 2 times, leaving a remainder of 288.
Write down 2 as next digit of the result. 
Result so far: 1422.0
If we subtract 802 from 1090, we get 288.
Grab the next digit (5) from the dividend, add it to 288, then carry on: 2885 / 401

Let's proceed to step 7:
If we divide 2885 by 401, we get 7 and a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 14227.0
Subtracting 2807 from 2885 leaves us with 78.
Take the next digit (7) from the dividend and append it to 78, then repeat: 787 / 401

Let's proceed to step 8:
401 can be fit into 787 1 times, resulting in a remainder of 386.
Use 1 as the next digit of our solution. 
Result so far: 142271.0
If we take 401 away from 787, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Moving on to step 9:
3860 divided by 401 is 9 with a remainder of 251.
The number 9 becomes the next digit in our result. 
Result so far: 142271.9
Subtract 3609 from 3860 to get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Going ahead to step 10:
401 goes into 2510 6 times with a remainder of 104.
Record the quotient 6 as the next digit in the result. 
Result so far: 142271.96
Deduct 2406 from 2510 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 11:
401 goes into 1040 2 times with a remainder of 238.
Record the quotient 2 as the next digit in the result. 
Result so far: 142271.962
If we take 802 away from 1040, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 12:
When dividing 2380 by 401, we get 5 with a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 142271.9625
The remainder is 375 after subtracting 2005 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 13:
If we divide 3750 by 401, we get 9 and a remainder of 141.
Put 9 as the next digit of the answer. 
Result so far: 142271.96259
The remainder is 141 after subtracting 3609 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 14:
401 goes into 1410 3 times with a remainder of 207.
Use 3 as the next digit of our solution. 
Result so far: 142271.962593
Subtracting 1203 from 1410 leaves us with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 15:
The number 401 fits into 2070 5 times, leaving a remainder of 65.
The next digit of our result is 5. 
Result so far: 142271.9625935
Deduct 2005 from 2070 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 16:
The number 401 fits into 650 1 times, leaving a remainder of 249.
Put 1 as the next digit of the answer. 
Result so far: 142271.96259351
Subtract 401 from 650 to get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

The quotient of the division is 142271.96259351, and the remainder is 2.49e-07.
