Let's divide 420372 by 55
We want to figure out the number of times 420372 can be divided by 55.

Advancing to step 1:
4 divided by 55 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 55

Moving on to step 2:
When dividing 42 by 55, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 55

Moving on to step 3:
55 goes into 420 7 times with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 385 away from 420, we end up with 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 55

Let's proceed to step 4:
55 can be fit into 353 6 times, resulting in a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 76.0
Deduct 330 from 353 and we're left with 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 55

Step 5:
55 can be fit into 237 4 times, resulting in a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 764.0
If we take 220 away from 237, we end up with 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 55

Advancing to step 6:
When dividing 172 by 55, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 7643.0
Deduct 165 from 172 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
When dividing 70 by 55, we get 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 7643.1
If we subtract 55 from 70, 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.

Step 8:
55 goes into 150 2 times with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 7643.12
If we take 110 away from 150, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
55 goes into 400 7 times with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 7643.127
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
150 divided by 55 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 7643.1272
The remainder is 40 after subtracting 110 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
400 divided by 55 is 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 7643.12727
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 12:
150 divided by 55 is 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 7643.127272
If we subtract 110 from 150, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
400 divided by 55 is 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 7643.1272727
Subtracting 385 from 400 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
55 goes into 150 2 times with a remainder of 40.
The next digit of our result is 2. 
Result so far: 7643.12727272
Deduct 110 from 150 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 7643.12727272 and a remainder of 4e-08.
