We're dividing 69515358 by 420 
Let's see how many times 420 fits into 69515358.

Step 1:
420 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 420

Moving on to step 2:
69 divided by 420 is 0 with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Grab the next digit (5) from the dividend, add it to 69, then carry on: 695 / 420

Let's proceed to step 3:
The number 420 fits into 695 1 times, leaving a remainder of 275.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 420 from 695 leaves us with 275.
Append the next digit (1) from the dividend to 275 and continue with: 2751 / 420

Let's proceed to step 4:
If we divide 2751 by 420, we get 6 and a remainder of 231.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 2520 from 2751 to get 231.
Take the next digit (5) from the dividend and append it to 231, then repeat: 2315 / 420

Advancing to step 5:
420 goes into 2315 5 times with a remainder of 215.
Record the quotient 5 as the next digit in the result. 
Result so far: 165.0
Subtracting 2100 from 2315 leaves us with 215.
Take the next digit (3) from the dividend and append it to 215, then repeat: 2153 / 420

Advancing to step 6:
If we divide 2153 by 420, we get 5 and a remainder of 53.
Use 5 as the next digit of our solution. 
Result so far: 1655.0
If we subtract 2100 from 2153, we get 53.
Grab the next digit (5) from the dividend, add it to 53, then carry on: 535 / 420

Step 7:
If we divide 535 by 420, we get 1 and a remainder of 115.
The next digit of our result is 1. 
Result so far: 16551.0
Deduct 420 from 535 and we're left with 115.
Take the next digit (8) from the dividend and append it to 115, then repeat: 1158 / 420

Moving on to step 8:
1158 divided by 420 is 2 with a remainder of 318.
Record the quotient 2 as the next digit in the result. 
Result so far: 165512.0
The remainder is 318 after subtracting 840 from 1158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Step 9:
3180 divided by 420 is 7 with a remainder of 240.
Record the quotient 7 as the next digit in the result. 
Result so far: 165512.7
Subtracting 2940 from 3180 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 10:
420 can be fit into 2400 5 times, resulting in a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 165512.75
The remainder is 300 after subtracting 2100 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 11:
If we divide 3000 by 420, we get 7 and a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 165512.757
The remainder is 60 after subtracting 2940 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
420 goes into 600 1 times with a remainder of 180.
The next digit of our result is 1. 
Result so far: 165512.7571
The remainder is 180 after subtracting 420 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 13:
420 can be fit into 1800 4 times, resulting in a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 165512.75714
If we take 1680 away from 1800, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 14:
420 can be fit into 1200 2 times, resulting in a remainder of 360.
The next digit of our result is 2. 
Result so far: 165512.757142
Subtracting 840 from 1200 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 15:
When dividing 3600 by 420, we get 8 with a remainder of 240.
Write down 8 as next digit of the result. 
Result so far: 165512.7571428
Subtract 3360 from 3600 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 16:
The number 420 fits into 2400 5 times, leaving a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 165512.75714285
If we subtract 2100 from 2400, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The quotient of the division is 165512.75714285, and the remainder is 3e-07.
