We're dividing 55397170 by 396 
We're looking to find how many times 396 goes into 55397170.

On to step 1:
396 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 396

On to step 2:
When dividing 55 by 396, we get 0 with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Take the next digit (3) from the dividend and append it to 55, then repeat: 553 / 396

Advancing to step 3:
If we divide 553 by 396, we get 1 and a remainder of 157.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 396 from 553, we get 157.
Append the next digit (9) from the dividend to 157 and continue with: 1579 / 396

Going ahead to step 4:
When dividing 1579 by 396, we get 3 with a remainder of 391.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 391 after subtracting 1188 from 1579.
Include the next digit (7) from the dividend after 391, then repeat: 3917 / 396

Advancing to step 5:
The number 396 fits into 3917 9 times, leaving a remainder of 353.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
If we take 3564 away from 3917, we end up with 353.
Grab the next digit (1) from the dividend, add it to 353, then carry on: 3531 / 396

Going ahead to step 6:
If we divide 3531 by 396, we get 8 and a remainder of 363.
The next digit of our result is 8. 
Result so far: 1398.0
Subtracting 3168 from 3531 leaves us with 363.
Append the next digit (7) from the dividend to 363 and continue with: 3637 / 396

On to step 7:
The number 396 fits into 3637 9 times, leaving a remainder of 73.
Write down 9 as next digit of the result. 
Result so far: 13989.0
Subtract 3564 from 3637 to get 73.
Append the next digit (0) from the dividend to 73 and continue with: 730 / 396

Going ahead to step 8:
When dividing 730 by 396, we get 1 with a remainder of 334.
Record the quotient 1 as the next digit in the result. 
Result so far: 139891.0
Deduct 396 from 730 and we're left with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Advancing to step 9:
396 goes into 3340 8 times with a remainder of 172.
Record the quotient 8 as the next digit in the result. 
Result so far: 139891.8
The remainder is 172 after subtracting 3168 from 3340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 10:
1720 divided by 396 is 4 with a remainder of 136.
Use 4 as the next digit of our solution. 
Result so far: 139891.84
If we subtract 1584 from 1720, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 11:
When dividing 1360 by 396, we get 3 with a remainder of 172.
Record the quotient 3 as the next digit in the result. 
Result so far: 139891.843
Subtracting 1188 from 1360 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 12:
396 goes into 1720 4 times with a remainder of 136.
Put 4 as the next digit of the answer. 
Result so far: 139891.8434
Deduct 1584 from 1720 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 13:
When dividing 1360 by 396, we get 3 with a remainder of 172.
Write down 3 as next digit of the result. 
Result so far: 139891.84343
Subtract 1188 from 1360 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 14:
If we divide 1720 by 396, we get 4 and a remainder of 136.
Put 4 as the next digit of the answer. 
Result so far: 139891.843434
Deduct 1584 from 1720 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 15:
1360 divided by 396 is 3 with a remainder of 172.
Use 3 as the next digit of our solution. 
Result so far: 139891.8434343
Deduct 1188 from 1360 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 16:
If we divide 1720 by 396, we get 4 and a remainder of 136.
The next digit of our result is 4. 
Result so far: 139891.84343434
Deduct 1584 from 1720 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

In conclusion, the division gives 139891.84343434 with a balance of 1.36e-07.
