We look at the division of 3777187 by 397 
Our goal is to divide 3777187 by 397.

Advancing to step 1:
The number 397 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 397

Going ahead to step 2:
397 can be fit into 37 0 times, resulting in a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Take the next digit (7) from the dividend and append it to 37, then repeat: 377 / 397

On to step 3:
The number 397 fits into 377 0 times, leaving a remainder of 377.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 377 to get 377.
Take the next digit (7) from the dividend and append it to 377, then repeat: 3777 / 397

Advancing to step 4:
3777 divided by 397 is 9 with a remainder of 204.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 204 after subtracting 3573 from 3777.
Bring next digit (1) of the dividend behind the 204 and repeat the process: 2041 / 397

Step 5:
397 can be fit into 2041 5 times, resulting in a remainder of 56.
Write down 5 as next digit of the result. 
Result so far: 95.0
If we subtract 1985 from 2041, we get 56.
Grab the next digit (8) from the dividend, add it to 56, then carry on: 568 / 397

Step 6:
If we divide 568 by 397, we get 1 and a remainder of 171.
The next digit of our result is 1. 
Result so far: 951.0
If we subtract 397 from 568, we get 171.
Bring next digit (7) of the dividend behind the 171 and repeat the process: 1717 / 397

Going ahead to step 7:
When dividing 1717 by 397, we get 4 with a remainder of 129.
The next digit of our result is 4. 
Result so far: 9514.0
Subtracting 1588 from 1717 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Let's proceed to step 8:
1290 divided by 397 is 3 with a remainder of 99.
Record the quotient 3 as the next digit in the result. 
Result so far: 9514.3
If we take 1191 away from 1290, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 9:
When dividing 990 by 397, we get 2 with a remainder of 196.
Put 2 as the next digit of the answer. 
Result so far: 9514.32
If we take 794 away from 990, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 10:
397 can be fit into 1960 4 times, resulting in a remainder of 372.
The next digit of our result is 4. 
Result so far: 9514.324
If we take 1588 away from 1960, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 11:
397 can be fit into 3720 9 times, resulting in a remainder of 147.
Record the quotient 9 as the next digit in the result. 
Result so far: 9514.3249
Deduct 3573 from 3720 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Advancing to step 12:
The number 397 fits into 1470 3 times, leaving a remainder of 279.
The number 3 becomes the next digit in our result. 
Result so far: 9514.32493
The remainder is 279 after subtracting 1191 from 1470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Step 13:
The number 397 fits into 2790 7 times, leaving a remainder of 11.
The next digit of our result is 7. 
Result so far: 9514.324937
Deduct 2779 from 2790 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
If we divide 110 by 397, we get 0 and a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 9514.324937
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 15:
1100 divided by 397 is 2 with a remainder of 306.
Put 2 as the next digit of the answer. 
Result so far: 9514.32493702
Deduct 794 from 1100 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

The final outcome is 9514.32493702, with a leftover of 3.06e-07.
