69669148 divided by 351 
Our goal is to divide 69669148 by 351.

On to step 1:
If we divide 6 by 351, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 351

Advancing to step 2:
When dividing 69 by 351, we get 0 with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Grab the next digit (6) from the dividend, add it to 69, then carry on: 696 / 351

Step 3:
351 can be fit into 696 1 times, resulting in a remainder of 345.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 351 from 696, we get 345.
Grab the next digit (6) from the dividend, add it to 345, then carry on: 3456 / 351

Going ahead to step 4:
The number 351 fits into 3456 9 times, leaving a remainder of 297.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 3159 from 3456 to get 297.
Fetch the next digit (9) from the dividend, attach it to 297 and continue: 2979 / 351

On to step 5:
351 goes into 2979 8 times with a remainder of 171.
Record the quotient 8 as the next digit in the result. 
Result so far: 198.0
Subtract 2808 from 2979 to get 171.
Include the next digit (1) from the dividend after 171, then repeat: 1711 / 351

Step 6:
If we divide 1711 by 351, we get 4 and a remainder of 307.
Use 4 as the next digit of our solution. 
Result so far: 1984.0
Subtracting 1404 from 1711 leaves us with 307.
Grab the next digit (4) from the dividend, add it to 307, then carry on: 3074 / 351

Moving on to step 7:
351 goes into 3074 8 times with a remainder of 266.
Use 8 as the next digit of our solution. 
Result so far: 19848.0
Subtracting 2808 from 3074 leaves us with 266.
Grab the next digit (8) from the dividend, add it to 266, then carry on: 2668 / 351

On to step 8:
351 goes into 2668 7 times with a remainder of 211.
Write down 7 as next digit of the result. 
Result so far: 198487.0
If we subtract 2457 from 2668, we get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

On to step 9:
If we divide 2110 by 351, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 198487.6
Deduct 2106 from 2110 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
The number 351 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 198487.6
If we subtract 0 from 40, 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 11:
351 can be fit into 400 1 times, resulting in a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 198487.601
If we subtract 351 from 400, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 12:
351 can be fit into 490 1 times, resulting in a remainder of 139.
The next digit of our result is 1. 
Result so far: 198487.6011
Deduct 351 from 490 and we're left with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

In conclusion, the division gives 198487.6011 with a balance of 0.00139.
