1671000 divided by 377 
The aim is to understand the frequency of 377 in 1671000.

Moving on to step 1:
377 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 377

Let's proceed to step 2:
When dividing 16 by 377, we get 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 377

Going ahead to step 3:
377 can be fit into 167 0 times, resulting in a remainder of 167.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 167, we get 167.
Fetch the next digit (1) from the dividend, attach it to 167 and continue: 1671 / 377

On to step 4:
1671 divided by 377 is 4 with a remainder of 163.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 1508 away from 1671, we end up with 163.
Take the next digit (0) from the dividend and append it to 163, then repeat: 1630 / 377

Moving on to step 5:
The number 377 fits into 1630 4 times, leaving a remainder of 122.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
If we subtract 1508 from 1630, we get 122.
Take the next digit (0) from the dividend and append it to 122, then repeat: 1220 / 377

Let's proceed to step 6:
1220 divided by 377 is 3 with a remainder of 89.
Record the quotient 3 as the next digit in the result. 
Result so far: 443.0
Subtracting 1131 from 1220 leaves us with 89.
Bring next digit (0) of the dividend behind the 89 and repeat the process: 890 / 377

Advancing to step 7:
890 divided by 377 is 2 with a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 4432.0
Subtracting 754 from 890 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 8:
377 goes into 1360 3 times with a remainder of 229.
Record the quotient 3 as the next digit in the result. 
Result so far: 4432.3
Subtract 1131 from 1360 to get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Let's proceed to step 9:
When dividing 2290 by 377, we get 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 4432.36
If we subtract 2262 from 2290, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
280 divided by 377 is 0 with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 4432.36
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 11:
377 goes into 2800 7 times with a remainder of 161.
The number 7 becomes the next digit in our result. 
Result so far: 4432.3607
If we take 2639 away from 2800, we end up with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Advancing to step 12:
377 can be fit into 1610 4 times, resulting in a remainder of 102.
Put 4 as the next digit of the answer. 
Result so far: 4432.36074
Subtracting 1508 from 1610 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 13:
The number 377 fits into 1020 2 times, leaving a remainder of 266.
The number 2 becomes the next digit in our result. 
Result so far: 4432.360742
Deduct 754 from 1020 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Advancing to step 14:
377 goes into 2660 7 times with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 4432.3607427
Subtract 2639 from 2660 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 15:
377 can be fit into 210 0 times, resulting in a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 4432.3607427
Deduct 0 from 210 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Our division results in 4432.3607427 with a remaining 2.1e-07.
