We look at the division of 53591240 by 377 
We want to figure out the number of times 53591240 can be divided by 377.

Going ahead to step 1:
377 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 377

On to step 2:
If we divide 53 by 377, we get 0 and a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 377

Going ahead to step 3:
If we divide 535 by 377, we get 1 and a remainder of 158.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 377 from 535 leaves us with 158.
Include the next digit (9) from the dividend after 158, then repeat: 1589 / 377

Going ahead to step 4:
377 can be fit into 1589 4 times, resulting in a remainder of 81.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 81 after subtracting 1508 from 1589.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 377

Step 5:
377 can be fit into 811 2 times, resulting in a remainder of 57.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
Subtracting 754 from 811 leaves us with 57.
Fetch the next digit (2) from the dividend, attach it to 57 and continue: 572 / 377

Advancing to step 6:
572 divided by 377 is 1 with a remainder of 195.
Use 1 as the next digit of our solution. 
Result so far: 1421.0
The remainder is 195 after subtracting 377 from 572.
Grab the next digit (4) from the dividend, add it to 195, then carry on: 1954 / 377

Step 7:
1954 divided by 377 is 5 with a remainder of 69.
Write down 5 as next digit of the result. 
Result so far: 14215.0
If we subtract 1885 from 1954, we get 69.
Take the next digit (0) from the dividend and append it to 69, then repeat: 690 / 377

Let's proceed to step 8:
377 goes into 690 1 times with a remainder of 313.
Record the quotient 1 as the next digit in the result. 
Result so far: 142151.0
Subtract 377 from 690 to get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Moving on to step 9:
If we divide 3130 by 377, we get 8 and a remainder of 114.
Record the quotient 8 as the next digit in the result. 
Result so far: 142151.8
Subtract 3016 from 3130 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 10:
377 can be fit into 1140 3 times, resulting in a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 142151.83
Deduct 1131 from 1140 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 11:
When dividing 90 by 377, we get 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 142151.83
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 12:
900 divided by 377 is 2 with a remainder of 146.
Put 2 as the next digit of the answer. 
Result so far: 142151.8302
The remainder is 146 after subtracting 754 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 13:
The number 377 fits into 1460 3 times, leaving a remainder of 329.
Put 3 as the next digit of the answer. 
Result so far: 142151.83023
Subtract 1131 from 1460 to get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

On to step 14:
377 can be fit into 3290 8 times, resulting in a remainder of 274.
The number 8 becomes the next digit in our result. 
Result so far: 142151.830238
Subtracting 3016 from 3290 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 15:
377 can be fit into 2740 7 times, resulting in a remainder of 101.
The next digit of our result is 7. 
Result so far: 142151.8302387
Subtracting 2639 from 2740 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 16:
The number 377 fits into 1010 2 times, leaving a remainder of 256.
The number 2 becomes the next digit in our result. 
Result so far: 142151.83023872
If we take 754 away from 1010, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final outcome is 142151.83023872, with a leftover of 2.56e-07.
