We look at the division of 21758160 by 345 
We want to divide 21758160 by 345.

Let's proceed to step 1:
2 divided by 345 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 345

Advancing to step 2:
The number 345 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 345

Going ahead to step 3:
345 goes into 217 0 times with a remainder of 217.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 217 leaves us with 217.
Include the next digit (5) from the dividend after 217, then repeat: 2175 / 345

Step 4:
345 goes into 2175 6 times with a remainder of 105.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 2070 from 2175, we get 105.
Bring next digit (8) of the dividend behind the 105 and repeat the process: 1058 / 345

Advancing to step 5:
If we divide 1058 by 345, we get 3 and a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 63.0
If we subtract 1035 from 1058, we get 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 345

Moving on to step 6:
When dividing 231 by 345, we get 0 with a remainder of 231.
Record the quotient 0 as the next digit in the result. 
Result so far: 630.0
The remainder is 231 after subtracting 0 from 231.
Take the next digit (6) from the dividend and append it to 231, then repeat: 2316 / 345

Going ahead to step 7:
345 goes into 2316 6 times with a remainder of 246.
The next digit of our result is 6. 
Result so far: 6306.0
Subtract 2070 from 2316 to get 246.
Grab the next digit (0) from the dividend, add it to 246, then carry on: 2460 / 345

Advancing to step 8:
345 goes into 2460 7 times with a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 63067.0
If we subtract 2415 from 2460, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 9:
345 can be fit into 450 1 times, resulting in a remainder of 105.
Write down 1 as next digit of the result. 
Result so far: 63067.1
If we subtract 345 from 450, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 10:
1050 divided by 345 is 3 with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 63067.13
If we subtract 1035 from 1050, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
The number 345 fits into 150 0 times, leaving a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 63067.13
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 12:
When dividing 1500 by 345, we get 4 with a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 63067.1304
If we subtract 1380 from 1500, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 13:
345 goes into 1200 3 times with a remainder of 165.
Use 3 as the next digit of our solution. 
Result so far: 63067.13043
If we subtract 1035 from 1200, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 14:
345 goes into 1650 4 times with a remainder of 270.
The number 4 becomes the next digit in our result. 
Result so far: 63067.130434
The remainder is 270 after subtracting 1380 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 15:
345 can be fit into 2700 7 times, resulting in a remainder of 285.
Put 7 as the next digit of the answer. 
Result so far: 63067.1304347
The remainder is 285 after subtracting 2415 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 16:
2850 divided by 345 is 8 with a remainder of 90.
Record the quotient 8 as the next digit in the result. 
Result so far: 63067.13043478
If we take 2760 away from 2850, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Our division results in 63067.13043478 with a remaining 9e-08.
