69719591 ÷ 421 
We're looking to find how many times 421 goes into 69719591.

On to step 1:
421 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 421

Step 2:
When dividing 69 by 421, we get 0 with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 69 to get 69.
Grab the next digit (7) from the dividend, add it to 69, then carry on: 697 / 421

Moving on to step 3:
421 goes into 697 1 times with a remainder of 276.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 421 from 697 and we're left with 276.
Append the next digit (1) from the dividend to 276 and continue with: 2761 / 421

On to step 4:
If we divide 2761 by 421, we get 6 and a remainder of 235.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 2526 from 2761 and we're left with 235.
Take the next digit (9) from the dividend and append it to 235, then repeat: 2359 / 421

Advancing to step 5:
421 can be fit into 2359 5 times, resulting in a remainder of 254.
Write down 5 as next digit of the result. 
Result so far: 165.0
If we take 2105 away from 2359, we end up with 254.
Take the next digit (5) from the dividend and append it to 254, then repeat: 2545 / 421

Advancing to step 6:
When dividing 2545 by 421, we get 6 with a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 1656.0
The remainder is 19 after subtracting 2526 from 2545.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 421

Going ahead to step 7:
421 can be fit into 199 0 times, resulting in a remainder of 199.
Put 0 as the next digit of the answer. 
Result so far: 16560.0
If we take 0 away from 199, we end up with 199.
Fetch the next digit (1) from the dividend, attach it to 199 and continue: 1991 / 421

On to step 8:
421 goes into 1991 4 times with a remainder of 307.
Write down 4 as next digit of the result. 
Result so far: 165604.0
Subtracting 1684 from 1991 leaves us with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Going ahead to step 9:
421 can be fit into 3070 7 times, resulting in a remainder of 123.
Record the quotient 7 as the next digit in the result. 
Result so far: 165604.7
Subtract 2947 from 3070 to get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 10:
If we divide 1230 by 421, we get 2 and a remainder of 388.
The number 2 becomes the next digit in our result. 
Result so far: 165604.72
If we take 842 away from 1230, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 11:
If we divide 3880 by 421, we get 9 and a remainder of 91.
Write down 9 as next digit of the result. 
Result so far: 165604.729
If we subtract 3789 from 3880, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 12:
910 divided by 421 is 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 165604.7292
Subtracting 842 from 910 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 13:
The number 421 fits into 680 1 times, leaving a remainder of 259.
The number 1 becomes the next digit in our result. 
Result so far: 165604.72921
Subtracting 421 from 680 leaves us with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Step 14:
If we divide 2590 by 421, we get 6 and a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 165604.729216
The remainder is 64 after subtracting 2526 from 2590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 15:
421 goes into 640 1 times with a remainder of 219.
The number 1 becomes the next digit in our result. 
Result so far: 165604.7292161
The remainder is 219 after subtracting 421 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Let's proceed to step 16:
When dividing 2190 by 421, we get 5 with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 165604.72921615
The remainder is 85 after subtracting 2105 from 2190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Our division results in 165604.72921615 with a remaining 8.5e-08.
