7435405 ÷ 391 
Our goal is to divide 7435405 by 391.

Let's proceed to step 1:
7 divided by 391 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 391

Advancing to step 2:
391 goes into 74 0 times with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Grab the next digit (3) from the dividend, add it to 74, then carry on: 743 / 391

Let's proceed to step 3:
391 goes into 743 1 times with a remainder of 352.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 352 after subtracting 391 from 743.
Append the next digit (5) from the dividend to 352 and continue with: 3525 / 391

Going ahead to step 4:
391 can be fit into 3525 9 times, resulting in a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 3519 from 3525 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 391

Let's proceed to step 5:
64 divided by 391 is 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
If we subtract 0 from 64, we get 64.
Grab the next digit (0) from the dividend, add it to 64, then carry on: 640 / 391

Advancing to step 6:
If we divide 640 by 391, we get 1 and a remainder of 249.
Write down 1 as next digit of the result. 
Result so far: 1901.0
Subtracting 391 from 640 leaves us with 249.
Append the next digit (5) from the dividend to 249 and continue with: 2495 / 391

Advancing to step 7:
The number 391 fits into 2495 6 times, leaving a remainder of 149.
Write down 6 as next digit of the result. 
Result so far: 19016.0
If we take 2346 away from 2495, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 8:
If we divide 1490 by 391, we get 3 and a remainder of 317.
Record the quotient 3 as the next digit in the result. 
Result so far: 19016.3
The remainder is 317 after subtracting 1173 from 1490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Moving on to step 9:
The number 391 fits into 3170 8 times, leaving a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 19016.38
If we subtract 3128 from 3170, we 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.

Moving on to step 10:
391 goes into 420 1 times with a remainder of 29.
The next digit of our result is 1. 
Result so far: 19016.381
If we take 391 away from 420, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 11:
391 goes into 290 0 times with a remainder of 290.
The number 0 becomes the next digit in our result. 
Result so far: 19016.381
Subtracting 0 from 290 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 12:
When dividing 2900 by 391, we get 7 with a remainder of 163.
Record the quotient 7 as the next digit in the result. 
Result so far: 19016.38107
If we take 2737 away from 2900, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Moving on to step 13:
391 goes into 1630 4 times with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 19016.381074
Deduct 1564 from 1630 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 14:
When dividing 660 by 391, we get 1 with a remainder of 269.
The number 1 becomes the next digit in our result. 
Result so far: 19016.3810741
Subtracting 391 from 660 leaves us with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Going ahead to step 15:
391 can be fit into 2690 6 times, resulting in a remainder of 344.
The next digit of our result is 6. 
Result so far: 19016.38107416
If we take 2346 away from 2690, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

The final outcome is 19016.38107416, with a leftover of 3.44e-07.
