78375545 ÷ 419 
We're looking to find how many times 419 goes into 78375545.

On to step 1:
419 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 419

Going ahead to step 2:
78 divided by 419 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Fetch the next digit (3) from the dividend, attach it to 78 and continue: 783 / 419

On to step 3:
783 divided by 419 is 1 with a remainder of 364.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 419 away from 783, we end up with 364.
Grab the next digit (7) from the dividend, add it to 364, then carry on: 3647 / 419

Step 4:
419 goes into 3647 8 times with a remainder of 295.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 3352 from 3647 leaves us with 295.
Fetch the next digit (5) from the dividend, attach it to 295 and continue: 2955 / 419

Moving on to step 5:
If we divide 2955 by 419, we get 7 and a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 187.0
Subtract 2933 from 2955 to get 22.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 419

Let's proceed to step 6:
225 divided by 419 is 0 with a remainder of 225.
The number 0 becomes the next digit in our result. 
Result so far: 1870.0
If we take 0 away from 225, we end up with 225.
Fetch the next digit (4) from the dividend, attach it to 225 and continue: 2254 / 419

Step 7:
2254 divided by 419 is 5 with a remainder of 159.
The next digit of our result is 5. 
Result so far: 18705.0
If we subtract 2095 from 2254, we get 159.
Take the next digit (5) from the dividend and append it to 159, then repeat: 1595 / 419

On to step 8:
1595 divided by 419 is 3 with a remainder of 338.
The number 3 becomes the next digit in our result. 
Result so far: 187053.0
If we take 1257 away from 1595, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 9:
If we divide 3380 by 419, we get 8 and a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 187053.8
The remainder is 28 after subtracting 3352 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
419 can be fit into 280 0 times, resulting in a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 187053.8
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 11:
419 can be fit into 2800 6 times, resulting in a remainder of 286.
Put 6 as the next digit of the answer. 
Result so far: 187053.806
The remainder is 286 after subtracting 2514 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 12:
When dividing 2860 by 419, we get 6 with a remainder of 346.
Use 6 as the next digit of our solution. 
Result so far: 187053.8066
If we take 2514 away from 2860, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

The final outcome is 187053.8066, with a leftover of 0.00346.
