58611221 ÷ 378 
We want to figure out the number of times 58611221 can be divided by 378.

Advancing to step 1:
5 divided by 378 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 378

Let's proceed to step 2:
When dividing 58 by 378, we get 0 with a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 58 to get 58.
Take the next digit (6) from the dividend and append it to 58, then repeat: 586 / 378

On to step 3:
378 can be fit into 586 1 times, resulting in a remainder of 208.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 208 after subtracting 378 from 586.
Bring next digit (1) of the dividend behind the 208 and repeat the process: 2081 / 378

Step 4:
378 goes into 2081 5 times with a remainder of 191.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 1890 from 2081, we get 191.
Append the next digit (1) from the dividend to 191 and continue with: 1911 / 378

Let's proceed to step 5:
The number 378 fits into 1911 5 times, leaving a remainder of 21.
The number 5 becomes the next digit in our result. 
Result so far: 155.0
Subtract 1890 from 1911 to get 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 378

Advancing to step 6:
378 can be fit into 212 0 times, resulting in a remainder of 212.
Put 0 as the next digit of the answer. 
Result so far: 1550.0
Deduct 0 from 212 and we're left with 212.
Append the next digit (2) from the dividend to 212 and continue with: 2122 / 378

Let's proceed to step 7:
If we divide 2122 by 378, we get 5 and a remainder of 232.
Record the quotient 5 as the next digit in the result. 
Result so far: 15505.0
If we take 1890 away from 2122, we end up with 232.
Append the next digit (1) from the dividend to 232 and continue with: 2321 / 378

Going ahead to step 8:
The number 378 fits into 2321 6 times, leaving a remainder of 53.
The number 6 becomes the next digit in our result. 
Result so far: 155056.0
If we take 2268 away from 2321, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 9:
The number 378 fits into 530 1 times, leaving a remainder of 152.
Put 1 as the next digit of the answer. 
Result so far: 155056.1
Subtract 378 from 530 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 10:
378 goes into 1520 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 155056.14
Subtract 1512 from 1520 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
The number 378 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 155056.14
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
378 can be fit into 800 2 times, resulting in a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 155056.1402
Deduct 756 from 800 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 13:
378 can be fit into 440 1 times, resulting in a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 155056.14021
If we subtract 378 from 440, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 14:
378 can be fit into 620 1 times, resulting in a remainder of 242.
Put 1 as the next digit of the answer. 
Result so far: 155056.140211
Subtracting 378 from 620 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

In conclusion, the division gives 155056.140211 with a balance of 2.42e-05.
