73286591 ÷ 391 
We want to divide 73286591 by 391.

Going ahead to step 1:
391 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 391

Let's proceed to step 2:
391 can be fit into 73 0 times, resulting in a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Take the next digit (2) from the dividend and append it to 73, then repeat: 732 / 391

Advancing to step 3:
391 goes into 732 1 times with a remainder of 341.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 391 from 732 leaves us with 341.
Take the next digit (8) from the dividend and append it to 341, then repeat: 3418 / 391

Moving on to step 4:
391 can be fit into 3418 8 times, resulting in a remainder of 290.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 3128 from 3418 and we're left with 290.
Bring next digit (6) of the dividend behind the 290 and repeat the process: 2906 / 391

Moving on to step 5:
391 goes into 2906 7 times with a remainder of 169.
The next digit of our result is 7. 
Result so far: 187.0
Deduct 2737 from 2906 and we're left with 169.
Append the next digit (5) from the dividend to 169 and continue with: 1695 / 391

Advancing to step 6:
391 can be fit into 1695 4 times, resulting in a remainder of 131.
The next digit of our result is 4. 
Result so far: 1874.0
Deduct 1564 from 1695 and we're left with 131.
Include the next digit (9) from the dividend after 131, then repeat: 1319 / 391

Going ahead to step 7:
If we divide 1319 by 391, we get 3 and a remainder of 146.
The number 3 becomes the next digit in our result. 
Result so far: 18743.0
If we subtract 1173 from 1319, we get 146.
Include the next digit (1) from the dividend after 146, then repeat: 1461 / 391

Advancing to step 8:
When dividing 1461 by 391, we get 3 with a remainder of 288.
Write down 3 as next digit of the result. 
Result so far: 187433.0
If we take 1173 away from 1461, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 9:
If we divide 2880 by 391, we get 7 and a remainder of 143.
Write down 7 as next digit of the result. 
Result so far: 187433.7
If we take 2737 away from 2880, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 10:
1430 divided by 391 is 3 with a remainder of 257.
Write down 3 as next digit of the result. 
Result so far: 187433.73
If we subtract 1173 from 1430, we get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Let's proceed to step 11:
391 goes into 2570 6 times with a remainder of 224.
The next digit of our result is 6. 
Result so far: 187433.736
If we subtract 2346 from 2570, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 12:
The number 391 fits into 2240 5 times, leaving a remainder of 285.
Write down 5 as next digit of the result. 
Result so far: 187433.7365
Subtracting 1955 from 2240 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 13:
391 goes into 2850 7 times with a remainder of 113.
Record the quotient 7 as the next digit in the result. 
Result so far: 187433.73657
Subtracting 2737 from 2850 leaves us with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 14:
391 can be fit into 1130 2 times, resulting in a remainder of 348.
Put 2 as the next digit of the answer. 
Result so far: 187433.736572
Subtracting 782 from 1130 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

On to step 15:
3480 divided by 391 is 8 with a remainder of 352.
Use 8 as the next digit of our solution. 
Result so far: 187433.7365728
The remainder is 352 after subtracting 3128 from 3480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 16:
When dividing 3520 by 391, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 187433.73657289
The remainder is 1 after subtracting 3519 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 187433.73657289 with a balance of 1e-09.
