We look at the division of 67464560 by 391 
Let's see how many times 391 fits into 67464560.

Let's proceed to step 1:
If we divide 6 by 391, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 391

Advancing to step 2:
The number 391 fits into 67 0 times, leaving a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Grab the next digit (4) from the dividend, add it to 67, then carry on: 674 / 391

Step 3:
391 can be fit into 674 1 times, resulting in a remainder of 283.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 391 from 674 and we're left with 283.
Grab the next digit (6) from the dividend, add it to 283, then carry on: 2836 / 391

Going ahead to step 4:
If we divide 2836 by 391, we get 7 and a remainder of 99.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 2737 from 2836 to get 99.
Include the next digit (4) from the dividend after 99, then repeat: 994 / 391

Let's proceed to step 5:
994 divided by 391 is 2 with a remainder of 212.
Use 2 as the next digit of our solution. 
Result so far: 172.0
The remainder is 212 after subtracting 782 from 994.
Grab the next digit (5) from the dividend, add it to 212, then carry on: 2125 / 391

Moving on to step 6:
The number 391 fits into 2125 5 times, leaving a remainder of 170.
Record the quotient 5 as the next digit in the result. 
Result so far: 1725.0
Deduct 1955 from 2125 and we're left with 170.
Append the next digit (6) from the dividend to 170 and continue with: 1706 / 391

Going ahead to step 7:
If we divide 1706 by 391, we get 4 and a remainder of 142.
Record the quotient 4 as the next digit in the result. 
Result so far: 17254.0
Subtract 1564 from 1706 to get 142.
Grab the next digit (0) from the dividend, add it to 142, then carry on: 1420 / 391

Let's proceed to step 8:
The number 391 fits into 1420 3 times, leaving a remainder of 247.
The number 3 becomes the next digit in our result. 
Result so far: 172543.0
Subtracting 1173 from 1420 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Step 9:
391 goes into 2470 6 times with a remainder of 124.
Record the quotient 6 as the next digit in the result. 
Result so far: 172543.6
The remainder is 124 after subtracting 2346 from 2470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 10:
1240 divided by 391 is 3 with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 172543.63
Deduct 1173 from 1240 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 11:
391 goes into 670 1 times with a remainder of 279.
Put 1 as the next digit of the answer. 
Result so far: 172543.631
Deduct 391 from 670 and we're left with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Moving on to step 12:
The number 391 fits into 2790 7 times, leaving a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 172543.6317
Subtract 2737 from 2790 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 13:
If we divide 530 by 391, we get 1 and a remainder of 139.
The number 1 becomes the next digit in our result. 
Result so far: 172543.63171
If we subtract 391 from 530, we get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Step 14:
1390 divided by 391 is 3 with a remainder of 217.
Put 3 as the next digit of the answer. 
Result so far: 172543.631713
If we subtract 1173 from 1390, we get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Advancing to step 15:
When dividing 2170 by 391, we get 5 with a remainder of 215.
Use 5 as the next digit of our solution. 
Result so far: 172543.6317135
If we take 1955 away from 2170, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 16:
391 can be fit into 2150 5 times, resulting in a remainder of 195.
Use 5 as the next digit of our solution. 
Result so far: 172543.63171355
Subtracting 1955 from 2150 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

The final outcome is 172543.63171355, with a leftover of 1.95e-07.
