We're dividing 72900645 by 377 
Our goal is to divide 72900645 by 377.

On to step 1:
If we divide 7 by 377, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 377

Advancing to step 2:
If we divide 72 by 377, we get 0 and a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Append the next digit (9) from the dividend to 72 and continue with: 729 / 377

Advancing to step 3:
729 divided by 377 is 1 with a remainder of 352.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 377 from 729 to get 352.
Append the next digit (0) from the dividend to 352 and continue with: 3520 / 377

Step 4:
3520 divided by 377 is 9 with a remainder of 127.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 3393 away from 3520, we end up with 127.
Append the next digit (0) from the dividend to 127 and continue with: 1270 / 377

Advancing to step 5:
When dividing 1270 by 377, we get 3 with a remainder of 139.
The number 3 becomes the next digit in our result. 
Result so far: 193.0
Subtract 1131 from 1270 to get 139.
Fetch the next digit (6) from the dividend, attach it to 139 and continue: 1396 / 377

Let's proceed to step 6:
1396 divided by 377 is 3 with a remainder of 265.
Put 3 as the next digit of the answer. 
Result so far: 1933.0
Subtracting 1131 from 1396 leaves us with 265.
Bring next digit (4) of the dividend behind the 265 and repeat the process: 2654 / 377

Step 7:
The number 377 fits into 2654 7 times, leaving a remainder of 15.
The next digit of our result is 7. 
Result so far: 19337.0
Subtract 2639 from 2654 to get 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 377

Going ahead to step 8:
When dividing 155 by 377, we get 0 with a remainder of 155.
Use 0 as the next digit of our solution. 
Result so far: 193370.0
The remainder is 155 after subtracting 0 from 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 9:
1550 divided by 377 is 4 with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 193370.4
Subtract 1508 from 1550 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
When dividing 420 by 377, we get 1 with a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 193370.41
Subtracting 377 from 420 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 11:
377 can be fit into 430 1 times, resulting in a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 193370.411
The remainder is 53 after subtracting 377 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final outcome is 193370.411, with a leftover of 0.0053.
